Description

Currently, if user copy file/dir from localFS or HDFS to swift object store, u/g/p will be gone. There should be a way to preserve u/g/p. It will provide benefit for a large number of files/dirs transferring between HDFS/localFS and Swift object store. We also need to be careful since Hadoop prevent general user from changing u/g/p especially if Kerberos is enabled.
