Subject [jira] Commented: (MAPREDUCE-1186) While localizing a DistributedCache file, TT sets permissions recursively on the whole base-dir
Date Tue, 05 Jan 2010 18:02:54 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1186?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12796788#action_12796788
] 

Hemanth Yamijala commented on MAPREDUCE-1186:
---------------------------------------------

Two minor nits before this is good to go:

- I would recommend we pull out the new code that sets up permission in TrackerDistributedCacheManager
into a separate method. localizeCache seems big enough to split
- I also think a test case that verifies permissions are only set for newly localized *public*
files is required for completeness of testing.
