Chris Douglas updated HADOOP-6143:
----------------------------------
Status: Open (was: Patch Available)
{noformat}
- <code> Returns 0 on success and -1 on error. </code></p>
+ <code> Returns 0 on success , and >0 if an error occurs.
</code></p>
{noformat}
Rather than test- or care- whether other platforms return -1, I would prefer
"nonzero on error" or more symmetrically, "nonzero on failure".
> FS shell commands returns incorrect exit code when error occurs
