Subject [jira] [Commented] (HADOOP-15599) Improve TrashPolicyDefault error message

Antal Mihalyi commented on HADOOP-15599:
----------------------------------------

Hi [~jojochuang] , right, we can improve the log further with this. I think we should only
log if we failed to parse the  "Current" format, and fallback for parsing the old format
(I suppose it is a rare occasion). We can extend the present "unexpected" log,stating that
we failed to parse both format, so we do not expect the directory in the .trash root. What
about that solution?
