PIG-3400 FS commands do not work with S3 paths
Review Request #13122 - Created July 31, 2013 and updated
Makes fs utility commands work with s3 paths. Documents fs utility commands in the Pig manual. (They were not documented at all.)
All unit tests pass. Manually verified the following commands with s3 paths: pig -e 'ls s3://<path>' pig -e 'mkdir s3://<path>' pig -e 'rm s3://<path>' pig -e 'cp s3://<path1> s3://<path2>' pig -e 'mv s3://<path1> s3://<path2>' pig -e 'copyToLocal s3://<path>/<file> .' pig -e 'copyFromLocal <file> s3://<path>'
