Subject [jira] Commented: (HADOOP-3578) mapred.system.dir should be accessible only to hadoop daemons
Date Mon, 27 Apr 2009 09:47:30 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3578?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12703046#action_12703046

Amar Kamat commented on HADOOP-3578:
------------------------------------

Kan,
This patch uploads job.jar to the staging area i.e ~/.staging/jobid/job.jar and creates a
symlink in DistributedCache. With this patch job.jar will be treated similar to libjars.

> Currently the jobclient accesses the {{mapred.system.dir}} to add job details. Hence
the {{mapred.system.dir}} has the permissions of {{rwx-wx-wx}}. This could be a security loophole
where the job files might get overwritten/tampered after the job submission.
