Github user HyukjinKwon commented on the issue:

https://github.com/apache/spark/pull/16098
  
I see. Let me please just revert the change back to 
https://github.com/apache/spark/pull/16098/commits/66ff918847a57b3ce4b5abbdf56498e3b871bbf0.
 It seems `TaskContextImpl.markTaskFailed(...)` should be called ahead when the 
task should be aborted (see https://issues.apache.org/jira/browse/SPARK-13601) 
and `Utils. tryWithSafeFinallyAndFailureCallbacks` calls this in `catchBlock`. 
I understand it seems not the cleanest way but it seems they can be refactored 
together if they have the same logics.

@srowen This is where try-with-resources is really useful in java.
Util.tryWithSafeFinallyAndFailureCallbacks is an attempt at doing that in 
scala with mixed results.

I agree, the formulation you proposed is cleaner - the code has migrated a 
bit since it was initially written using tryWithSafeFinallyAndFailureCallbacks

Github user mridulm commented on the issue:

https://github.com/apache/spark/pull/16098
  
That looks like a bug in ParquetRecordWriter (the contract of close() is 
unambiguous) ... but then, I guess there is no point in fighting against buggy 
code : we have to integrate with a lot of Closeable's.
If this is common enough bug, my suggestion is a bad idea - thanks for 
verifying.

Btw, if you are depending on writer being null to prevent 'double close', 
copy it to a local variable, null it and close the local variable. This 
prevents close itself throwing exception masking the initial exception.

2016-12-01 Thread HyukjinKwon
Github user HyukjinKwon commented on the issue:

https://github.com/apache/spark/pull/16098
  
Ah, @marmbrus thanks for pointing that out. I see close should be 
idempotent by design but I am worried if it is guaranteed that they actually 
are. I mean.. for example, `ParquetRecordWriter`'s `close()` is not idempotent 
up to my understanding because at least it'd throw `NullPointerException` 
currently when we try to close multiple times.

For example, If we close this via 
[ParquetRecordWriter.close()](https://github.com/apache/parquet-mr/blob/apache-parquet-1.8.0/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ParquetRecordWriter.java#L110-L116)
 which calls [InternalParquetRecordWriter. 
flushRowGroupToStore()](https://github.com/apache/parquet-mr/blob/apache-parquet-1.8.0/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/InternalParquetRecordWriter.java#L155-L175)
  through 
[InternalParquetRecordWriter.close()](https://github.com/apache/parquet-mr/blob/apache-parquet-1.8.0/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/InternalParquetRecordWriter.java#L113),
 it would throws at least `NullPointerException` as the column store 
(containing column writers) becomes `null` for the first close().

close is idempotent - simply close it before 
'committer.commitTask(taskContext)' and you should be done. The second close in 
finally will become no-op in case of successful commit, and will handle failure 
cases.
