--------------------------------------
Hi, [~xiaochen]
Could you give another look of 02 patch?
bq. could you please add a line to {{-setPolicy}}
This document already indicates that:
{noformat}
`path`: An directory in HDFS. This is a mandatory parameter. Setting a
policy only affects newly created files, and does not affect existing files.
{noformat}
I feel that it is sufficient. What do you think?
Thanks!
