Hemanth Yamijala commented on MAPREDUCE-856:
--------------------------------------------

bq. User directory can be 570. So also distributed cache directory (no need 
even for setuid, right ?)

I meant setgid.. However, that may be required, as we realized in an internal 
discussion.

> Localized files from DistributedCache should have right access-control
