Chris Nauroth updated HDFS-6039:
--------------------------------
Attachment: HDFS-6039.1.patch
This patch fixes the bug by skipping copy of the default ACL during renames.
This is consistent with the behavior of Linux ACLs. If you rename an existing
file or directory underneath a directory that has a default ACL, then it
doesn't copy the default ACL. The renamed file or directory retains its
existing ACL (or plain permissions).
I added 2 new tests in {{FSAclBaseTest}} to cover renames of files and
directories. I also added a CLI test that replicates what Yesha reported.
These tests failed before applying the patch, and then passed afterwards.
