Description

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.
