> With metafile configuration, one can configure sharelib (eg. pig_latest) to latest version available.
> If new version is available, admin will just change the pig_latest sysmlink to new version. 
> There will be no change to Oozie or metafile configuration.
> Oozie should be able to detect symlink change and reloads the sharelib.
> metafile configuration can look like
> oozie.pig_latest=hdfs:///tmp/pig_latest
> where /tmp/pig_latest is a symlink pointing to latest available version.
