Sreejith MV updated HDFS-13003:
-------------------------------
Summary: Access time should be considered when setTimes is called on a
dir (was: [OIV] Irrelevant access time for the dirs when run with Delimited
option )
Description:
Access time for a directory can be modified with
DistributedFileSystem.setTimes().
But this changed access time is not stored in the fsimage.
After restart of namenode, it will be lost and reset as zero.
