slfan1989 merged PR #8759:
URL: https://github.com/apache/hadoop/pull/8759
> hadoop-mapreduce-client-jobclient tests jar cannot run sleep and most of its
> other programs
> -------------------------------------------------------------------------------------------
>
> Key: MAPREDUCE-7546
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7546
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: client, test
> Affects Versions: 3.5.0
> Environment: Since 3.5.0, hadoop jar
> hadoop-mapreduce-client-jobclient-*-tests.jar lists only 5 of its 29
> programs, after a NoSuchMethodException for TestTextInputFormat.main. Running
> any of the other programs, for example sleep -m 1 -r 1, fails with "Unknown
> program" and exit code 255. The other missing programs include nnbench,
> TestDFSIO, SliveTest, fail, largesorter and minicluster.
> Expected: the jar lists all its programs without errors, and sleep and the
> others run again. This was broken by MAPREDUCE-7421.
> This surfaces in a testing harness that I made for testing HADOOP-19972
> locally.
