Raghu Angadi commented on HADOOP-2420:
--------------------------------------
Thanks Dhruba. {{serialVersionUID}} is from {{java.io.Serializeable}}
interface. If I don't define one, Ecplipse shows an annoying warning. It is
strictly not required.
> 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.
