Dibyendu Karmakar commented on HDFS-13453:
------------------------------------------
Thanks [~elgoiri].
Using this above mentioned approach, when mount table will have */parent* as
well as */parent/child* mount point it will return the modified date of
*/parent/child* for */parent*. But the actual modified date of /parent will be
different in mount table entry. I think if we have /parent in mount table we
should return the actual modified date present in the mount table. When /parent
will not be there in mount table, in that case we will return modified date of
/parent/child.
What do you suggest?

> [HDFS-13386|https://issues.apache.org/jira/browse/HDFS-13386] is not handling
> the case when /parent in not present in mount table but /parent/subdir is in
> mount table.
> In this case getMountPointDates is not able to fetch the latest time for
> /parent as /parent is not present in mount table.
> For this scenario we will display latest modified subdir date/time as /parent
> modified time.
