Robert Joseph Evans commented on HADOOP-7432:
---------------------------------------------
It looks like the change was made as part of HADOOP-3953. Implement sticky bit
for directories in HDFS. (Jakob Homan via szetszwo)
There were a lot of other changes too associated with that patch, could you
please revert it back to "%04o". It should not make any difference in the
actual operation of the chmod command, but it will be more consistent with what
is actually supported by 0.20-security.
> Back-port HADOOP-7110 to 0.20-security

> HADOOP-7110 implemented chmod in the NativeIO library so we can have good
> performance (ie not fork) and still not be prone to races. This should fix
> build failures (and probably task failures too).
