[ https://issues.apache.org/jira/browse/MAPREDUCE-2547?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13041358#comment-13041358 ]
Konstantin Boudnik commented on MAPREDUCE-2547:
-----------------------------------------------
Steps to reproduce:
- setup cluster from [these bits|https://builds.apache.org/job/Hadoop-22-Build/]
- apply [simple configs|https://github.com/rvs/hdeploy/tree/master/conf]
- start cluster
- run TestDFSIO:
{noformat}
$HADOOP_HOME/bin/hadoop jar $HADOOP_HOME/hadoop-mapred-test-0.22.0-SNAPSHOT.jar TestDFSIO -write -nrFiles 100 -fileSize 10MB
{noformat}
> TestDFSIO failes on a physical cluster
> --------------------------------------
>
> Key: MAPREDUCE-2547
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2547
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: test
> Affects Versions: 0.22.0
> Environment: Physical cluster based on 0.22-SNAPSHOT
> Reporter: Konstantin Boudnik
> Priority: Blocker
>
> An attempt to run TestDSFIO on cluster fails because TestDFSIO tries to run MR job with local runner. If JT is explicitly specified via {{-jt}} cmd. arg. then everything is working as expected.
