dfs "Rename failed" doesn't give reason if source doesn't exist
---------------------------------------------------------------
Key: HADOOP-3529
URL: https://issues.apache.org/jira/browse/HADOOP-3529
Project: Hadoop Core
Issue Type: Bug
Affects Versions: 0.16.3
Reporter: Michael Bieniosek
If I run
hadoop fs -mv /no/such/file /blah
I get the error: mv: Rename failed /no/such/file
But in the namenode log, it says
2008-06-10 21:17:37,883 WARN org.apache.hadoop.dfs.StateChange: DIR*
FSDirectory.unprotectedRenameTo: failed to rename /no/such/file to /blah
because source does not exist
It would be nice if the fs shell also gave the informative error.
