Barna Zsombor Klara commented on HIVE-15168:
--------------------------------------------
i'm not sure these failures are related.
These are known flaky tests:
explainanalyze_2 - https://issues.apache.org/jira/browse/HIVE-15084
transform_ppr2 - https://issues.apache.org/jira/browse/HIVE-15201
orc_ppd_schema_evol_3a - https://issues.apache.org/jira/browse/HIVE-14936
These are failing rather consistently:
union_fast_stats - https://issues.apache.org/jira/browse/HIVE-15115
join_acid_non_acid - https://issues.apache.org/jira/browse/HIVE-15116
auto_sortmerge_join_2 - is not identified as flaky, but the failure is in MR, I
don't think my changes to the SparkClient could have caused it. And it did not
fail on the first run.
{code}
< FAILED: Execution Error, return code 3 from
org.apache.hadoop.hive.ql.exec.mr.MapredLocalTask
< ATTEMPT: Execute BackupTask: org.apache.hadoop.hive.ql.exec.mr.MapRedTask
{code}
This leaves TestSparkCliDriver, which I cannot repro locally.
>From the test report it seems to me that the error is happening during the
>test setup:
{code}
java.lang.AssertionError: Failed during createSources processLine with code=3
{code}
But the hive log has a different failure:
{code}
2016-11-21T08:36:57,751 INFO [stderr-redir-1] client.SparkClientImpl: 16/11/21
08:36:57 WARN TaskSetManager: Lost task 0.0 in stage 46.0 (TID 53,
10.234.144.78): java.io.IOException: Failed to create local dir in
/tmp/spark-8a7bd913-fca5-4990-ad09-c9eff4dacae0/executor-e85f9833-b0ab-47ed-bb95-56dc9ef64177/blockmgr-044ca916-76f1-402f-80ed-c4ec5fd4d544/2b.
{code}
I'm not sure if either can be related to the refactoring in the SparkClientImpl.
