Raghu Angadi updated HADOOP-2420:
---------------------------------
Attachment: HADOOP-2420.patch
Patch attached. Uses exit code from ShellCommandExecutor. '1' is the only
expected exit code. Unusual errors like 'command not found' result in different
exit codes (127 on my Linux box).
> Use exit code to detect normal errors while excuting 'ls' in Local FS

> Local FileSystem runs {{ls -ld}} find file permissions, owner and group for a
> file. Currently it parses message in the exception to check if the command
> returned an error due to expected conditions like missing file.
> HADOOP-2344 add interface to get error code returned by the external process.
> Local FS should use that.
