Uma Maheswara Rao G commented on HDFS-2712:
-------------------------------------------
1st Patch : HDFS-2712
1) UnsupportedActionException will be thrown if we try to setTimes on
directories
2) Moved the atime field to iNodeFile obj.
3) also moved atime down to iNodeSymlink, i am not sure whether really a time
required on iNodeSymlink. But not to break any functionality, i just added
atime to it as well.
Thanks

> 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 ).
