Dmitriy V. Ryaboy commented on PIG-943:
---------------------------------------
Daniel,
-1 is a bit of a hack. Maybe cleaner to insert and check for nulls? Also,
perhaps using stringToLong from CastUtils is warranted as it's a bit safer than
parseLong().
-D
> Pig crash when it cannot get counter from hadoop

> We see following call stacks in Pig:
> Case 1:
> Caused by: java.lang.NullPointerException
> at
> org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher.computeWarningAggregate(MapReduceLauncher.java:390)
> at
> org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher.launchPig(MapReduceLauncher.java:238)
> at
> org.apache.pig.backend.hadoop.executionengine.HExecutionEngine.execute(HExecutionEngine.java:265)
> Case 2:
> Caused by: java.lang.NullPointerException
> at
> org.apache.pig.tools.pigstats.PigStats.accumulateMRStats(PigStats.java:150)
> at
> org.apache.pig.tools.pigstats.PigStats.accumulateStats(PigStats.java:91)

> at
> org.apache.pig.backend.hadoop.executionengine.HExecutionEngine.execute(HExecutionEngine.java:265)
> In both cases, hadoop jobs finishes without error. The cause of both problems
> is RunningJob.getCounters() returns a null, and Pig do not currently check
> for that.
