[SPARK-15706][SQL] Fix Wrong Answer when using IF NOT EXISTS in INSERT 
OVERWRITE for DYNAMIC PARTITION

 What changes were proposed in this pull request?
`IF NOT EXISTS` in `INSERT OVERWRITE` should not support dynamic partitions. If 
we specify `IF NOT EXISTS`, the inserted statement is not shown in the table.

This PR is to issue an exception in this case, just like what Hive does. Also 
issue an exception if users specify `IF NOT EXISTS` if users do not specify any 
`PARTITION` specification.

 How was this patch tested?
Added test cases into `PlanParserSuite` and `InsertIntoHiveTableSuite`

Author: gatorsmile 

Closes #13447 from gatorsmile/insertIfNotExist.

[SPARK-15822] [SQL] Prevent byte array backed classes from referencing freed 
memory

## What changes were proposed in this pull request?
`UTF8String` and all `Unsafe*` classes are backed by either on-heap or off-heap 
byte arrays. The code generated version `SortMergeJoin` buffers the left hand 
side join keys during iteration. This was actually problematic in off-heap mode 
when one of the keys is a `UTF8String` (or any other 'Unsafe*` object) and the 
left hand side iterator was exhausted (and released its memory); the buffered 
keys would reference freed memory. This causes Seg-faults and all kinds of 
other undefined behavior when we would use one these buffered keys.

This PR fixes this problem by creating copies of the buffered variables. I have 
added a general method to the `CodeGenerator` for this. I have checked all 
places in which this could happen, and only `SortMergeJoin` had this problem.

This PR is largely based on the work of robbinspg and he should be credited for 
this.

## How was this patch tested?
Manually tested on problematic workloads.

[SPARK-15782][YARN] Fix spark.jars and spark.yarn.dist.jars handling

When `--packages` is specified with spark-shell the classes from those packages 
cannot be found, which I think is due to some of the changes in SPARK-12343.

Tested manually with both scala 2.10 and 2.11 repls.

vanzin davies can you guys please review?

[SPARK-15991] SparkContext.hadoopConfiguration should be always the base of 
hadoop conf created by SessionState

## What changes were proposed in this pull request?
Before this patch, after a SparkSession has been created, hadoop conf set 
directly to SparkContext.hadoopConfiguration will not affect the hadoop conf 
created by SessionState. This patch makes the change to always use 
SparkContext.hadoopConfiguration  as the base.

This patch also changes the behavior of hive-site.xml support added in 
https://github.com/apache/spark/pull/12689/. With this patch, we will load 
hive-site.xml to SparkContext.hadoopConfiguration.

## How was this patch tested?
New test in SparkSessionBuilderSuite.

Author: Yin Huai 

Closes #13711 from yhuai/SPARK-15991.

spark git commit: [SPARK-15991] SparkContext.hadoopConfiguration should be always the base of hadoop conf created by SessionState

[SPARK-15991] SparkContext.hadoopConfiguration should be always the base of 
hadoop conf created by SessionState

## What changes were proposed in this pull request?
Before this patch, after a SparkSession has been created, hadoop conf set 
directly to SparkContext.hadoopConfiguration will not affect the hadoop conf 
created by SessionState. This patch makes the change to always use 
SparkContext.hadoopConfiguration  as the base.

This patch also changes the behavior of hive-site.xml support added in 
https://github.com/apache/spark/pull/12689/. With this patch, we will load 
hive-site.xml to SparkContext.hadoopConfiguration.

## How was this patch tested?
New test in SparkSessionBuilderSuite.

Author: Yin Huai 

Closes #13711 from yhuai/SPARK-15991.

[SPARK-15749][SQL] make the error message more meaningful

## What changes were proposed in this pull request?

For table test1 (C1 varchar (10), C2 varchar (10)), when I insert a row using
```
sqlContext.sql("insert into test1 values ('abc', 'def', 1)")
```
I got error message

```
Exception in thread "main" java.lang.RuntimeException: RelationC1#0,C2#1 
JDBCRelation(test1)
requires that the query in the SELECT clause of the INSERT INTO/OVERWRITE 
statement
generates the same number of columns as its schema.
```
The error message is a little confusing. In my simple insert statement, it 
doesn't have a SELECT clause.

I will change the error message to a more general one

```
Exception in thread "main" java.lang.RuntimeException: RelationC1#0,C2#1 
JDBCRelation(test1)
requires that the data to be inserted have the same number of columns as the 
target table.
```

## How was this patch tested?

I tested the patch using my simple unit test, but it's a very trivial change 
and I don't think I need to check in any test.

spark git commit: [SPARK-15868][WEB UI] Executors table in Executors tab should sort Executor IDs in numerical order

[andrewor14]

Repository: spark
Updated Branches:
  refs/heads/branch-2.0 fb0fab63c -> 27e274c3e


[SPARK-15868][WEB UI] Executors table in Executors tab should sort Executor IDs 
in numerical order

## What changes were proposed in this pull request?

Currently the Executors table sorts by id using a string sort (since that's 
what it is stored as). Since  the id is a number (other than the driver) we 
should be sorting numerically. I have changed both the initial sort on page 
load as well as the table sort to sort on id numerically, treating non-numeric 
strings (like the driver) as "-1"

## How was this patch tested?

[SPARK-15868][WEB UI] Executors table in Executors tab should sort Executor IDs 
in numerical order

## What changes were proposed in this pull request?

Currently the Executors table sorts by id using a string sort (since that's 
what it is stored as). Since  the id is a number (other than the driver) we 
should be sorting numerically. I have changed both the initial sort on page 
load as well as the table sort to sort on id numerically, treating non-numeric 
strings (like the driver) as "-1"

## How was this patch tested?

[MINOR][DOCS][SQL] Fix some comments about types(TypeCoercion,Partition) and 
exceptions.

## What changes were proposed in this pull request?

This PR contains a few changes on code comments.
- `HiveTypeCoercion` is renamed into `TypeCoercion`.
- `NoSuchDatabaseException` is only used for the absence of database.
- For partition type inference, only `DoubleType` is considered.

[SPARK-15998][SQL] Verification of SQLConf HIVE_METASTORE_PARTITION_PRUNING

 What changes were proposed in this pull request?
`HIVE_METASTORE_PARTITION_PRUNING` is a public `SQLConf`. When `true`, some 
predicates will be pushed down into the Hive metastore so that unmatching 
partitions can be eliminated earlier. The current default value is `false`. For 
performance improvement, users might turn this parameter on.

So far, the code base does not have such a test case to verify whether this 
`SQLConf` properly works. This PR is to improve the test case coverage for 
avoiding future regression.

output=[a#234L,b#235L,count(c)#247L,max(c)#248L])
```

After:

```
*HashAggregate(keys=[a#234L, b#235L], functions=[count(1), max(c#236L)], 
output=[a#234L, b#235L, count(c)#247L, max(c)#248L])
```

## How was this patch tested?

Manually tested.

spark git commit: [SPARK-15975] Fix improper Popen retcode code handling in dev/run-tests

[andrewor14]

Repository: spark
Updated Branches:
  refs/heads/branch-1.6 cffc0800b -> 0a8ada506


[SPARK-15975] Fix improper Popen retcode code handling in dev/run-tests

In the `dev/run-tests.py` script we check a `Popen.retcode` for success using 
`retcode > 0`, but this is subtlety wrong because Popen's return code will be 
negative if the child process was terminated by a signal: 
https://docs.python.org/2/library/subprocess.html#subprocess.Popen.returncode

In order to properly handle signals, we should change this to check `retcode != 
0` instead.

Author: Josh Rosen 

Closes #13692 from JoshRosen/dev-run-tests-return-code-handling.

spark git commit: [SPARK-15978][SQL] improve 'show tables' command related codes

[SPARK-15978][SQL] improve 'show tables' command related codes

## What changes were proposed in this pull request?

I've found some minor issues in "show tables" command:

1. In the `SessionCatalog.scala`, `listTables(db: String)` method will call 
`listTables(formatDatabaseName(db), "*")` to list all the tables for certain 
db, but in the method `listTables(db: String, pattern: String)`, this db name 
is formatted once more. So I think we should remove
`formatDatabaseName()` in the caller.

2. I suggest to add sort to listTables(db: String) in InMemoryCatalog.scala, 
just like listDatabases().

## How was this patch tested?

The existing test cases should cover it.

[SPARK-15796][CORE] Reduce spark.memory.fraction default to avoid overrunning 
old gen in JVM default config

## What changes were proposed in this pull request?

Reduce `spark.memory.fraction` default to 0.6 in order to make it fit within 
default JVM old generation size (2/3 heap). See JIRA discussion. This means a 
full cache doesn't spill into the new gen. CC andrewor14

## How was this patch tested?

Jenkins tests.

[SPARK-15922][MLLIB] `toIndexedRowMatrix` should consider the case `cols < 
offset+colsPerBlock`

## What changes were proposed in this pull request?

SPARK-15922 reports the following scenario throwing an exception due to the 
mismatched vector sizes. This PR handles the exceptional case, `cols < (offset 
+ colsPerBlock)`.

**Before**
```scala
scala> import org.apache.spark.mllib.linalg.distributed._
scala> import org.apache.spark.mllib.linalg._
scala> val rows = IndexedRow(0L, new DenseVector(Array(1,2,3))) :: 
IndexedRow(1L, new DenseVector(Array(1,2,3))):: IndexedRow(2L, new 
DenseVector(Array(1,2,3))):: Nil
scala> val rdd = sc.parallelize(rows)
scala> val matrix = new IndexedRowMatrix(rdd, 3, 3)
scala> val bmat = matrix.toBlockMatrix
scala> val imat = bmat.toIndexedRowMatrix
scala> imat.rows.collect
... // java.lang.IllegalArgumentException: requirement failed: Vectors must be 
the same length!
```

**After**
```scala
...
scala> imat.rows.collect
res0: Array[org.apache.spark.mllib.linalg.distributed.IndexedRow] = 
Array(IndexedRow(0,[1.0,2.0,3.0]), IndexedRow(1,[1.0,2.0,3.0]), 
IndexedRow(2,[1.0,2.0,3.0]))
```

## How was this patch tested?

Pass the Jenkins tests (including the above case)

[SPARK-15977][SQL] Fix TRUNCATE TABLE for Spark specific datasource tables

## What changes were proposed in this pull request?
`TRUNCATE TABLE` is currently broken for Spark specific datasource tables 
(json, csv, ...). This PR correctly sets the location for these datasources 
which allows them to be truncated.

## How was this patch tested?
Extended the datasources `TRUNCATE TABLE` tests in `DDLSuite`.

Author: Herman van Hovell 

Closes #13697 from hvanhovell/SPARK-15977.

[SPARK-15981][SQL][STREAMING] Fixed bug and added tests in DataStreamReader 
Python API

## What changes were proposed in this pull request?

- Fixed bug in Python API of DataStreamReader.  Because a single path was being 
converted to a array before calling Java DataStreamReader method (which takes a 
string only), it gave the following error.
```
File "/Users/tdas/Projects/Spark/spark/python/pyspark/sql/readwriter.py", line 
947, in pyspark.sql.readwriter.DataStreamReader.json
Failed example:
json_sdf = spark.readStream.json(os.path.join(tempfile.mkdtemp(), 'data'),  
   schema = sdf_schema)
Exception raised:

[SPARK-15996][R] Fix R examples by removing deprecated functions

## What changes were proposed in this pull request?

Currently, R examples(`dataframe.R` and `data-manipulation.R`) fail like the 
following. We had better update them before releasing 2.0 RC. This PR updates 
them to use up-to-date APIs.

```bash
$ bin/spark-submit examples/src/main/r/dataframe.R
...
Warning message:
'createDataFrame(sqlContext...)' is deprecated.
Use 'createDataFrame(data, schema = NULL, samplingRatio = 1.0)' instead.
See help("Deprecated")
...
Warning message:
'read.json(sqlContext...)' is deprecated.
Use 'read.json(path)' instead.
See help("Deprecated")
...
Error: could not find function "registerTempTable"
Execution halted
```

## How was this patch tested?

Manual.
```
curl -LO http://s3-us-west-2.amazonaws.com/sparkr-data/flights.csv
bin/spark-submit examples/src/main/r/dataframe.R
bin/spark-submit examples/src/main/r/data-manipulation.R flights.csv
```

[SPARK-15996][R] Fix R examples by removing deprecated functions

## What changes were proposed in this pull request?

Currently, R examples(`dataframe.R` and `data-manipulation.R`) fail like the 
following. We had better update them before releasing 2.0 RC. This PR updates 
them to use up-to-date APIs.

```bash
$ bin/spark-submit examples/src/main/r/dataframe.R
...
Warning message:
'createDataFrame(sqlContext...)' is deprecated.
Use 'createDataFrame(data, schema = NULL, samplingRatio = 1.0)' instead.
See help("Deprecated")
...
Warning message:
'read.json(sqlContext...)' is deprecated.
Use 'read.json(path)' instead.
See help("Deprecated")
...
Error: could not find function "registerTempTable"
Execution halted
```

## How was this patch tested?

Manual.
```
curl -LO http://s3-us-west-2.amazonaws.com/sparkr-data/flights.csv
bin/spark-submit examples/src/main/r/dataframe.R
bin/spark-submit examples/src/main/r/data-manipulation.R flights.csv
```

[SPARK-15983][SQL] Removes FileFormat.prepareRead

## What changes were proposed in this pull request?

Interface method `FileFormat.prepareRead()` was added in #12088 to handle a 
special case in the LibSVM data source.

However, the semantics of this interface method isn't intuitive: it returns a 
modified version of the data source options map. Considering that the LibSVM 
case can be easily handled using schema metadata inside `inferSchema`, we can 
remove this interface method to keep the `FileFormat` interface clean.

## How was this patch tested?

Existing tests.

Author: Cheng Lian 

Closes #13698 from liancheng/remove-prepare-read.

[SPARK-15862][SQL] Better Error Message When Having Database Name in CACHE 
TABLE AS SELECT

 What changes were proposed in this pull request?
~~If the temp table already exists, we should not silently replace it when 
doing `CACHE TABLE AS SELECT`. This is inconsistent with the behavior of `CREAT 
VIEW` or `CREATE TABLE`. This PR is to fix this silent drop.~~

~~Maybe, we also can introduce new syntax for replacing the existing one. For 
example, in Hive, to replace a view, the syntax should be like `ALTER VIEW AS 
SELECT` or `CREATE OR REPLACE VIEW AS SELECT`~~

The table name in `CACHE TABLE AS SELECT` should NOT contain database prefix 
like "database.table". Thus, this PR captures this in Parser and outputs a 
better error message, instead of reporting the view already exists.

In addition, refactoring the `Parser` to generate table identifiers instead of 
returning the table name string.

 How was this patch tested?
- Added a test case for caching and uncaching qualified table names
- Fixed a few test cases that do not drop temp table at the end
- Added the related test case for the issue resolved in this PR

[3/3] spark git commit: [SPARK-15979][SQL] Rename various Parquet support classes (branch-2.0).

[rxin]

[SPARK-15979][SQL] Rename various Parquet support classes (branch-2.0).

## What changes were proposed in this pull request?
This patch renames various Parquet support classes from CatalystAbc to 
ParquetAbc. This new naming makes more sense for two reasons:

1. These are not optimizer related (i.e. Catalyst) classes.
2. We are in the Spark code base, and as a result it'd be more clear to call 
out these are Parquet support classes, rather than some Spark classes.

## How was this patch tested?
Renamed test cases as well.

Author: Reynold Xin 

Closes #13700 from rxin/parquet-rename-branch-2.0.
