Extensions to FsShell
---------------------
Key: MAPREDUCE-2404
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2404
Project: Hadoop Map/Reduce
Issue Type: Improvement
Affects Versions: 0.20.3
Reporter: Olga Natkovich
Our project, Pig, exposes FsShell functionality to our end users through a
shell command. We want to use this command with no modifications to make sure
that whether you work with HDFS through Hadoop or Pig you get identical
semantics.
The main concern that has been recently raised by our users is that there is no
way to ignore certain failures that they consider to be benign, for instance,
removing a non-existent directory.
We have 2 asks related to this issue:
(1) Meaningful error code returned from FsShell (we use java class) so that we
can take different actions on different errors
(2) Unix like ways to tell the command to ignore certain behavior. Here are the
commands that we would like to be expanded/implemented:
* rm -f
* rmdir ---ignore-fail-on-non-empty
* mkdir -p
