Peeyush Bishnoi updated HADOOP-4705:
------------------------------------
Attachment: hadoop-4705.txt
HoD created temp directories are with permissions 0700 because pbsdsh process ,
whose umask(0077), launches hodring tasks on computes nodes , further this
launched hodring's creates the temp-dir and work-dirs on compute nodes with
permission 0700.
As temp-dir and work-dirs having a permission of 0700 , it is not feasible for
application like Chukwa to have access for files and directories inside this
temp-dir for gathering hadoop metrics.
So this patch will explicitly set the umask(0022) on hodring process so as to
create the temp-dir and work-dirs with permission 0755 .

> When HOD creates the log, work and temp directories for Hadoop, it creates
> them with permissions 0700. This is too restrictive for applications like
> Chukwa which need access to files in this directory for generating Hadoop
> metrics. This is a request to allow read permissions to other applications.
