Zhenxiao Luo commented on HIVE-2804:
------------------------------------
By creating an ThrowNullPointer UDF, and running it in MiniMRCluster, could
reproduce a MapReduce job failing.
When running on apache trunk(which is using MR1), get the following error
message:
[junit] Begin query: throw_npe.q
[junit] Error during job, obtaining debugging information...
[junit] Examining task ID: task_20120426165633901_0001_m_000002 (and more) from

And in the output file:
PREHOOK: Output:

Ended Job = job_20120426165633901_0001 with errors
FAILED: Execution Error, return code 2 from
org.apache.hadoop.hive.ql.exec.MapRedTask
So, on apache trunk, TaskLog retrieval is working OK.
Since our CDH4 branch could not run MiniMRCluster yet, will try on an MR2
cluster, and also try to run a local cluster in pseudo-distributed mode.
> Task log retrieval fails on secure cluster
