[jira] [Updated] (MAPREDUCE-7546) 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.
> Reporter: Jose Luis López
> Assignee: Jose Luis López
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.5.1, 3.6.0
