[jira] Commented: (MAPREDUCE-744) Support in DistributedCache to share cache files with other users after HADOOP-4493

    [ https://issues.apache.org/jira/browse/MAPREDUCE-744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12786279#action_12786279 ] 

Devaraj Das commented on MAPREDUCE-744:
---------------------------------------

I should add that "public" means world-readable. The entire hierarchy of the cache file path is checked for that (starting from the leaf filename to "/").
