History files are given world readable permissions.
---------------------------------------------------
Key: HADOOP-4783
URL: https://issues.apache.org/jira/browse/HADOOP-4783
Project: Hadoop Core
Issue Type: Bug
Components: mapred
Reporter: Hemanth Yamijala
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.
