> After the dicussion in HDFS-2436, unsupported behaviour for setTimes was intentional
(HADOOP-1869).
> But current INode structure hierarchy seems, it supports atime for directories also.
But as per HADOOP-1869, we are supporting only for files. To avoid the confusions, we can
move the atime fields to INodeFile as we planned to support setTimes only for files. And also
restrict the support for setTimes on directories ( which is implemented with HDFS-2436 ).
