Amareshwari Sriramadasu commented on HADOOP-4783:
-------------------------------------------------

I would propose we have 0710 permission for history directory and 0740 permission for history
files, sothat clients like Chukwa and Hadoop-vaidya would read history files. Thoughts?

> It is found that history files are being created with permissions 0777. On shared clusters
this is opening up too much. However, there is a requirement to allow Chukwa to read history
files. (See HADOOP-4705). This issue is to set up appropriate permissions for the files to
be as restrictive as required, while still fixing the problem for Chukwa.
