["Nigel Daley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-3891?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12630330#action_12630330 ] 

Nigel Daley commented on HADOOP-3891:
-------------------------------------

The fix for this should include some new test cases added to src/test/org/apache/hadoop/cli/testConf.xml (which is run by TestCLI)

>
> When the replication # is larger than dfs.replication.max (defined in conf), "fs -setrep" shows a meaningless error message.  For example,
> {noformat}
> //dfs.replication.max is 512
> $ hadoop fs -setrep 1000 r.txt
> setrep: java.io.IOException: file /user/tsz/r.txt.
> {noformat}
