Mahesh Raju Somalaraju commented on TEZ-4725:
---------------------------------------------
Afer fixing the above two flaky tests i observed some other tests failed due to
these changes. So i put the details related all the failed test here and
pushing as part of this JIRA.
1)TestAMRecoveryAggregationBroadcast.testMapJoinTemporalFailure
Failure:expected: <1> but was:<0> in recovery log assertions
Root Cause:Fixed Thread.sleep(10s) before AM kill — TABLE_SCAN/AGGREGATION may
not finish in 10s on a loaded CI node
2)TestAMRecoveryAggregationBroadcast.*
Failure: IllegalArgumentException: port out of range:-1
Root Cause: New AM container allocated (state=RUNNING) but rpcPort==-1; guard
only checked == 0
3)TestHistoryParser.testParserWithSuccessfulJob
Failure:JSONException: A JSONObject text must begin with '{'
Root Cause: ATS flush lag + ZipOutputStream not closed on exception = empty zip
entry read by parser
4)TestMRRJobsDAGApi.testMultipleMRRSleepJobViaSession
Failure:expected: <READY> but was:<RUNNING>
Root Cause: DAG SUCCEEDED ≠ AM session READY; cleanup window visible on slow CI
5)TestMRRJobsDAGApi.testNonDefaultFSStagingDir
Failure: test timed out after 60000ms in waitNonSessionTillReady
Root Cause: waitNonSessionTillReady() had no deadline; looped forever when AM
port was not yet bound
6)TestMRRJobsDAGApi.testMRRSleepJobDagSubmit (and siblings)
Failure:test timed out after 60000ms
Same root cause; @Test(timeout=60000) fired before the new 120s internal
deadline
> TestAMRecoveryAggregationBroadcast.testMapJoinTemporalFailure is flaky
