Uma Maheswara Rao G updated HDFS-2712:
--------------------------------------
Description:
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 ).

After the dicussion in HDFS-2436, unsupported behaviour for setTimes was
intentional (HADOOP-1869).
But current INode structure hierarchy seems, it supports atime and mtime for
directories also. But as per HADOOP-1869, we are supporting only for files. To
avoid the confusions, we can move the mtime and 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 ).
Summary: setTimes should support only for files and move the atime
field down to iNodeFile. (was: setTimes should support only for files and move
the mtime&atime fields down to iNodeFile.)
