2016-10-17 Thread rxin
Github user rxin commented on the issue:

https://github.com/apache/spark/pull/15493
  
Why not just introduce a crossJoin function in R, similar to 
Python/Scala/Java?

We don't want to change the default join type, because it is still valid to 
run an inner join by specifying a predicate later using the filter operator.

--- End diff --

Ok, but it's really not that complicated or difficult to understand.

There is only one way to add stages to `failedStages`: within the 
`FetchFailed` case.  When a `failedStage` is added to `failedStages`, it is 
always accompanied by the parent `mapStage`.

There are only two ways to remove stages from `failedStages`: 1) within the 
handling of a `ResubmitFailedStages` event, when the entire `failedStages` is 
cleared; 2) within `cleanupStateForJobAndIndependentStages` when we call 
`removeStage`.  Obviously, 1) can't produce a state where `mapStage` is not in 
`failedStage` while a corresponding `failedStage` is, so the only logic we need 
to concern ourselves with is in 2).

In order for 2) to produce a state where `mapStage` is absent from 
`failedStages` while an associated `failedStage` is present, `removeStage` 
would need to have been called on the `mapStage` while not being called on the 
`failedStage`.  But that can't happen because `removeStage` will not be called 
on a stage unless no Job needs that stage anymore.  If no job needs the 
`mapStage`, then no job can need a `failedStage` that uses the output of that 
`mapStage` -- i.e. it is not possible that a `mapStage` will be removed in 
`cleanupStateForJobAndIndependentStages` unless every associated `failedStage` 
will also be removed.

Conclusion: It is never possible for `mapStage` to be absent from 
`failedStages` at the same time that `failedStages` is present, so the proposed 
`|| !failedStages.contains(mapStage)` condition will never be checked -- it 
would just be unreachable and misleading code.

There also isn't really any need for concern over lack of tests.  There is 
no need to prove correctness of the current code for something that can't 
happen presently, so the only point of such a test would be to guard against 
some future mistaken change making it possible to remove a failed `mapStage` 
while some `failedStage` still needs it.  If that happens, then we've got far 
bigger problems than checking whether we need to issue a new 
`ResubmitFailedStages` event, and checks for that kind of broken removal of 
parents while their children are still depending onthem should be covered in 
the tests of `cleanupStateForJobAndIndependentStages`.

[SPARK-17974] Refactor FileCatalog classes to simplify the inheritance tree

## What changes were proposed in this pull request?

This renames `BasicFileCatalog => FileCatalog`, combines  
`SessionFileCatalog` with `PartitioningAwareFileCatalog`, and removes the old 
`FileCatalog` trait.

In summary,
```
MetadataLogFileCatalog extends PartitioningAwareFileCatalog
ListingFileCatalog extends PartitioningAwareFileCatalog
PartitioningAwareFileCatalog extends FileCatalog
TableFileCatalog extends FileCatalog
```

@rxin @marmbrus I am think of merging this PR (with the ignored flaky test) 
to make it consistent with the master. So that follow up PRs (flaky test fix, 
further API changes) can be merged on both master and branch 2.0. Any 
objections?

[GitHub] spark issue #15497: [Test][SPARK-16002][Follow-up] Fix flaky test in Streami...

2016-10-17 Thread tdas
Github user tdas commented on the issue:

https://github.com/apache/spark/pull/15497
  
I thought about it, and I still dont like this design. This is adding more 
complexity in a general class ManualClock, for functionality needed only by 
StreamExecution. And that leads to these sort of question - should the general 
feature like `isThreadWaiting` work with multiple threads, etc. 

I think we need to do it differently. I think its best to create a custom 
ManualClock for StreamExecution, which adds the functionality necessary for 
StreamExecution.

Mind if I take over this PR and work this out (in the interest of time, 
2.0.2 cutoff is imminent)?

[GitHub] spark issue #11119: [SPARK-10780][ML] Add an initial model to kmeans

2016-10-17 Thread sethah
Github user sethah commented on the issue:

https://github.com/apache/spark/pull/9
  
I agree that saving the initialModel may not be practical - since it can be 
large. However, not saving that param at all also seems a bit contrary to me. 
When we produce a model from an estimator, we copy over the params that were 
used to create the model. These params give an indication to how the model was 
created. If we completely disregard the initialModel when we save the model, 
then it will appear as though the model was not created with an initialModel. 
In fact for kmeans, it would look like the model was created using the 
`k-means||` initialization strategy since that is the default. This is 
misleading.

It would be nice to have a way to avoid saving the model with the initial 
model data, but still preserve the information about how the model was 
initialized. You can argue even, that the initialModel should not be a param at 
all because of the edge cases it seems to introduce.

[GitHub] spark issue #15421: [SPARK-17811] SparkR cannot parallelize data.frame with ...

2016-10-17 Thread shivaram
Github user shivaram commented on the issue:

https://github.com/apache/spark/pull/15421
  
Thanks @wangmiao1981 - There are two different kinds of serializations that 
happen in SparkR - one is the RPC style serialization where function arguments 
are serialized using `writeDate`, `writeInt` etc. The other is batch or bulk 
serialization that we use in case of converting R `data.frame` to Spark RDDs. 
This is used in the `createDataFrame` case from [1].

Now the way this is supposed to work is that this is converted by the call 
to `lapply` and `getJRDD` [2] to be a row-wise serialized `SparkDataFrame`. To 
do this on the executor side you will have a `unserialize` called on the bulk 
data  [3] and a `writeRowSerialize` called for each row [4]. So the final byte 
stream to look at is the one here. But my guess is that things are going wrong 
somewhere before this -- i.e. the byte stream at [3] for example has some 
different type or something like that. Or to put it another way, are we sure 
`writeString` was called with `NA` or was it some other function like 
`writeBin` because the types were wrong ?

The other reason for such a transient bug might be that the channels are 
not getting flushed somewhere and this doesn't show up on some R versions. But 
yeah your debugging methods are in line with what I would try

2016-10-17 Thread MLnick
Github user MLnick commented on the issue:

https://github.com/apache/spark/pull/9
  
Good points. Perhaps a solution - while slightly "verbose", is to introduce 
another param `initialModelWriteMode` which governs what is saved - `full`, 
`params` or `none`. Full is obviously the entire model, `params` is the 
metadata only without the data, while `none` is not saved at all.

[SPARK-13747][SQL]Fix concurrent executions in ForkJoinPool for SQL

## What changes were proposed in this pull request?

Calling `Await.result` will allow other tasks to be run on the same thread 
when using ForkJoinPool. However, SQL uses a `ThreadLocal` execution id to 
trace Spark jobs launched by a query, which doesn't work perfectly in 
ForkJoinPool.

This PR just uses `Awaitable.result` instead to  prevent ForkJoinPool from 
running other tasks in the current waiting thread.

## How was this patch tested?

2016-10-17 Thread tdas
GitHub user tdas opened a pull request:

https://github.com/apache/spark/pull/15519

[SQL][STREAMING][TEST] Fix flaky tests in StreamingQueryListenerSuite

This work has largely been done by @lw-lin in his PR #15497. This is a 
slightly refactoring of it.

## What changes were proposed in this pull request?
There were two sources of flakiness in StreamingQueryListener test.

- When testing with manual clock, consecutive attempts to advance the clock 
can occur without the stream execution thread being unblocked and doing some 
work between the two attempts. Hence the following can happen with the current 
ManualClock.
```
+---++
|  StreamExecution thread   | testing thread |
+---++
|  ManualClock.waitTillTime(100) {  ||
|_isWaiting = true  ||
|wait(10)   ||
|still in wait(10)  |  if (_isWaiting) advance(100)  |
|still in wait(10)  |  if (_isWaiting) advance(200)  | <- 
this should be disallowed !
|still in wait(10)  |  if (_isWaiting) advance(300)  | <- 
this should be disallowed !
|  wake up from wait(10)||
|   current time is 600 ||
|   _isWaiting = false  ||
|  }||
+---++
```

- Second source of flakiness is that the adding data to memory stream may 
get processing in any trigger, not just the first trigger.


My fix is to make the manual clock wait for the other stream execution 
thread to start waiting for the clock at the right wait start time. That is, 
`advance(300)` (see above) will wait for stream execution thread to complete 
the wait that started at time 100, and start a new wait at time 300 (i.e. time 
stamp after the previous `advance(200)`).

In addition, since this is a feature that is solely used by 
StreamExecution, I removed all the non-generic code from ManualClock and put 
them in StreamManualClock inside StreamTest.


## How was this patch tested?
Ran existing unit test MANY TIME in Jenkins

@shivaram  Thanks for your explanation! I can continue debugging this as 
you pointed and I can constantly reproduce the issue. For this PR, I think it 
is fine for handling the `NA` in the backend except for the unnecessary 
exception handling. I can submit a follow up PR on the serialization part.

In an earlier version, it was the "root" path of the table, excluding any

Now I'd say it could be reverted to `paths`.

We're not expecting a `ParquetRelation2` anymore—more like a

The cases you enumerated are the ones I was thinking of. The changes 
introduced here would alleviate those problems, I agree. What I'm wondering is 
if this problem still exists in other cases. If Derrick had 1.3M data points 
and asked for 10k clusters, and got only 1k unique cluster centers, why did it 
happen? Is it common/possible for clusters that start in different locations to 
converge to the same point? I'd be interested to replicate this issue, not sure 
if I will have the time.

Also, I'm slightly inclined to match scikit or R unless we're certain of a 
clear benefit not to.

[SPARK-17980] [SQL] Fix refreshByPath for converted Hive tables

## What changes were proposed in this pull request?

There was a bug introduced in https://github.com/apache/spark/pull/14690 
which broke refreshByPath with converted hive tables (though, it turns out it 
was very difficult to refresh converted hive tables anyways, since you had to 
specify the exact path of one of the partitions).

This changes refreshByPath to invalidate by prefix instead of exact match, 
and fixes the issue.

cc @sameeragarwal for refreshByPath changes
@mallman 

## How was this patch tested?

Extended unit test.
