Review request for hive, chengxiang li and Xuefu Zhang.


Bugs: HIVE-9152
https://issues.apache.org/jira/browse/HIVE-9152


Repository: hive-git


Description
---

Tez implemented dynamic partition pruning in HIVE-7826. This is a nice 
optimization and we should implement the same in HOS.

Yes you're right. However, the only usage for this is in SplitOpTreeForDPP, in 
which we pass a set as parameter. So it should only contain unique operators.

targetWorkID/sourceWorkID are unique. We need random number because we could 
have multiple tasks for a particular work, in which case they may overwrite 
each other's file.

Yes targetWorkID/sourceWorkID should be unique, but it could have multiple 
tasks from a single work, and if we don't have the random number, their results 
may overwrite each other. We also did the same thing for the hash table sink in 
Spark, and we haven't seen any issue with that.

Actually there could be a diamond shape in the operator graph such as that 
formed by demux and mux operators. Join operator is another example. We should 
use graph traverse instead of tree traverse.

Maybe there is a problem as you described, but I think that's irrelavent to the 
work here. Thus, we should create a separate JIRA to fix that instead of 
including it here.

I guess I don't know enough to comment on this, but looking at 
VectorReduceSinkOperator and VectorAppMasterEventOperator I can see some 
prominent differences:

1. first batch detection and processing there
2. VectorizedSerde logic here

Probably a live review will help.

Isn't this is the last operator in the operator graph? If so, we don't need

Random.nextint() doesn't gives uniqueness. If targetWorkID/sourceWorkID gives 
you uniqueness, then you don't need a random number, right? If 
targetWorkID/sourceWorkID doesn't give uniqueness, then adding a random number 
doesn't help much.

fs.create() can be successful, while either "new BufferedOutputStream()" or 
"new ObjectOutputStream()" can fail (returning null). In that case, the file 
descriptor returned by fs.create() will leak.

There is a new notation in java 7 for automatic resource management. Refer to:

Take FilterOperator for example, the worst case is, it may just half the input 
rows as its statistic, you can find the rule for FilterOperator at 
FilterStatsRule, so it's a bad news that estimated statistics is not always 
conservative, this would make the threshold does not work as expected 
sometimes. You may create a followup work for this if it changes a lot.

Review request for hive, chengxiang li and Xuefu Zhang.


Bugs: HIVE-9152
https://issues.apache.org/jira/browse/HIVE-9152


Repository: hive-git


Description
---

Tez implemented dynamic partition pruning in HIVE-7826. This is a nice 
optimization and we should implement the same in HOS.

Switching to runtime would be very different - here we want to check this 
threshold, and avoid generating the pruning task if possible.
How inaccurate the stats would be? I'm fine if it's always more conservative.

This is because a target work with a partitioned table could have multiple 
partition columns which could come from multiple table and/or partkeys.
You can check test output file for some examples.

Yes, this would be an improvement. Xuefu and me talked about adding an extra 
parameter to control the generated file size. We plan to do that as a follow-up 
task.

OK, I changed this to assert, since it would be a bug if # of fields is not 1 
here.

The only difference is the type of pruning sink added - we use 
SparkPartitionPruningSinkOp while Tez uses AppMasterEventOp.
OK, I'll reuse the existing class.

Yea, but I guess it doesn't matter here. We just use this to find the enclosing 
work for a op, and we just need to find at least one root op.
Duplicate doesn't matter here I think.

This is done before we clone the branch:

```

no - because it is a transient field.

It shouldn't - I think work ID and Random#nextInt() should both be unique, 
right?

Not much we can do here, since here the processing is more complicated. I 
changed part of the code to call the super.process().

Can you explain a little under which situation this would happen? and what is 
the better way to do this? Thanks.

This is to prevent a newly generated task to be processed again. In case the 
task contains localwork, it maybe overwritten. See HIVE-9424 for more details.
However, I just found out that this is also fixed as part of HIVE-9659, so I'll 
remove this code now.

This is because even though we are cloning the op tree, we are still retaining 
the old work. So, after we've created a new root op, we need to
update the rootToWorkMap, and map the cloned root op to the old work. This is 
later used in getEnclosingWork.
We also need to keep the old entry because in SparkPartitionPruningSink, it 
still stores the old TableScanOperator, and in processPartitionPruningSink it
will look up the op to get a corresponding target work.
Added more comments in the code.

It shouldn't - it'a tree traversing and every operator should only be added 
once.

It could equal to 0, since getInputPaths() could return 0. This would result an 
IAE from newFixedThreadPool.

This is to delay stats annotation until we've done the DPP optimization. The 
generated branches also need to be annotated with stats.

This is because we moved the stats annotation to SparkCompiler, and therefore 
in SimpleFetchOptimizer, the fetch task generated won't have the stats.
I don't see this is a big issue and Tez does the same thing as well.

ql/src/java/org/apache/hadoop/hive/ql/optimizer/SparkRemoveDynamicPruningBySize.java
 (line 59)


The statistic data shoud be quite unaccurate after filter and group, as 
it's computered based on estimation during compile time. I think threshold 
verification on unaccurate data should be unacceptable as that means the 
threshold may not work at all.
We may check this threshold in SparkPartitionPruningSinkOperator at runtime.



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/GenSparkUtils.java (line 396)


Why we need List for table/cloumnname/partkey here? do we support multi 
PartitionPruningSinkOperator inside single operator tree?



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/SparkPartitionPruningSinkOperator.java
 (line 61)


While append data size overwhelm its capability, DataOutputBuffer expand 
its byte array size by create a new byte array with 2x size and copy old one to 
new one. A estimated initial byte array size should be able to reduce most 
array copy.

Log in error level should means some error happens,the process would be 
interrupted, if we really expect single field here, should we throw an 
exception while it has more? otherwise, we should downgrade the log level to 
WARN with more precise information.

itests/src/test/resources/testconfiguration.properties (line 894)


Are there more test cases that can be turned on?



ql/src/java/org/apache/hadoop/hive/ql/exec/vector/VectorSparkPartitionPruningSinkOperator.java
 (line 68)


I think we should delegate the processing to the parent when processing one 
row from the batch. Refer to VectorReduceSinkOperator for an example.



ql/src/java/org/apache/hadoop/hive/ql/optimizer/SparkDynamicPartitionPruningOptimization.java
 (line 74)


Is there anything specific to Spark? If not, we should probably reuse 
rather than copying.



ql/src/java/org/apache/hadoop/hive/ql/optimizer/SparkRemoveDynamicPruningBySize.java
 (line 45)


Same as above. We should probably reuse.



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/GenSparkUtils.java (line 375)


Instead of throwing an AssertionError, should we do a condition assertion 
instead?



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/GenSparkUtils.java (line 589)


It seems that an operator might be visited multiple times.



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/SparkCompiler.java (line 219)


The comment here is a little confusing. "break op tree" seems having 
already happened above.



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/SparkCompiler.java (line 224)


Nit: add comments here, like "regenerate task dependency".



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/SparkCompiler.java (line 262)


Rename generateWorkTree() to generateTaskTreeHelper() or something like 
that.



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/SparkPartitionPruningOptimizer.java
 (line 71)


Rename the class to something like OperatorTreeSplitterForPPD().



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/SparkPartitionPruningOptimizer.java
 (line 81)


Nit: Split this into two lines instead.



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/SparkPartitionPruningOptimizer.java
 (line 107)


For the cloned tree, don't we need to remove the branches that's not 
connected to the pruning sink operator, i.e., RS->Join?



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/SparkPartitionPruningOptimizer.java
 (line 111)


This is not cloned as part of cloneOperatorTree()?



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/SparkPartitionPruningSinkOperator.java
 (line 69)


Nit: remove the blank line.



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/SparkPartitionPruningSinkOperator.java
 (line 92)


Can we still get conflicts in the file name?



ql/src/java/org/apache/hadoop/hive/ql/parse/spark/SparkPartitionPruningSinkOperator.java
 (line 98)


Nit: Potential leak of BufferedOutputStream.

This a big patch, for a big feature. It's hard to review offline. Here I 
offered about things that are obvious. For better understanding, I think an 
in-person review would be more effective.


ql/if/queryplan.thrift


I'm not sure if it matters, but it's probably better if we add it as the 
last.



ql/src/java/org/apache/hadoop/hive/ql/exec/GroupByOperator.java


Did you make any changes in this file? If not, let's leave it as it is.



ql/src/java/org/apache/hadoop/hive/ql/exec/spark/SparkDynamicPartitionPruner.java


File descriptor needs to be closed in final block. In addition, closing in 
is not sufficient, as in might be null while fs.open(fstatus.getPath() returns 
not null.



ql/src/java/org/apache/hadoop/hive/ql/exec/spark/SparkUtilities.java


Any chance that an op might be visited multiple times?



ql/src/java/org/apache/hadoop/hive/ql/io/CombineHiveInputFormat.java


numThread could be <= 0?



ql/src/java/org/apache/hadoop/hive/ql/optimizer/Optimizer.java


what's this change about?



ql/src/test/results/clientpositive/spark/smb_mapjoin_11.q.out


why the stats are gone?

Tez implemented dynamic partition pruning in HIVE-7826. This is a nice 
optimization and we should implement the same in HOS.
