Subject [jira] [Commented] (YARN-578) NodeManager should use SecureIOUtils for serving logs and intermediate outputs
Date Tue, 30 Apr 2013 04:44:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-578?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13645240#comment-13645240
] 

Vinod Kumar Vavilapalli commented on YARN-578:
----------------------------------------------

Can you use this only for YARN changes i.e. serving logs and open a separate MAPREDUCE ticket
for ShuffleHandler?

For the YARN changes:
 - Remove the comment above the code which talks about SecureIOUtils ;)
 - I think we should separate the exception message to clearly say whether this was an permission-issue
or something else.

> Log servlets for serving logs and the ShuffleService for serving intermediate outputs
both should use SecureIOUtils for avoiding symlink attacks.
