"fs -setrep" should have better error message
---------------------------------------------
Key: HADOOP-3891
URL: https://issues.apache.org/jira/browse/HADOOP-3891
Project: Hadoop Core
Issue Type: Improvement
Components: dfs
Reporter: Tsz Wo (Nicholas), SZE
When the replication # is large 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}
