[jira] Commented: (MAPREDUCE-1457) For secure job execution, couple

Posted by "Hudson (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/MAPREDUCE-1457?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12830708#action_12830708 ]
Hudson commented on MAPREDUCE-1457:
-----------------------------------
Integrated in Hadoop-Mapreduce-trunk-Commit #228 (See [http://hudson.zones.apache.org/hudson/job/Hadoop-Mapreduce-trunk-Commit/228/])
. Fixes JobTracker to get the FileSystem object within getStagingAreaDir within a privileged block. Fixes Child.java to use the appropriate UGIs while getting the TaskUmbilicalProtocol proxy and while executing the task. Contributed by Jakob Homan.

Regarding addition of new tests, the bugs fixed by the patch shows up in only the secure environment (and hence difficult to write testcases). The patch was manually tested.

Devaraj Das commented on MAPREDUCE-1457:
----------------------------------------
Ok the individual changes:
1) In the JobTracker, the getStagingArea RPC needs to construct a path for the user to write job files to. The getStagingArea does a getFileSystem and internally the getFileSystem sets up a connection to the namenode. For this connection, the JobTracker's credential should be used. That's why the mrOwner.doAs in that method is required.
2) In Child.java, the task authenticates to the TaskTracker using the jobtoken. The username in the jobtoken is jobId. The doAs block done using taskOwner is required so that the username mentioned in the token and the one doing the operation matches.
3) In Child.java, the task execution and the task cleanup are within doAs blocks and those doAs blocks are run as the user submitting the job. In the former part, the task communicates with the namenode, and in the latter, it could potentially communicate with the namenode (abortTask creates a connection to the namenode, etc). These are within doAs blocks so that the username mentioned in the delegation token (the job submitting user) matches with the user performing the operation.

Devaraj Das commented on MAPREDUCE-1457:
----------------------------------------
Some comments:
In the trunk patch and in the Y20 patch, the call to task.taskCleanup in Child.java should be within a privileged block.
In the Y20 patch, the calls to JobHistory.initDone() and JobHistory.init() should be within privileged blocks, and use the JobTracker's ugi. Within JobHistory.logSubmitted, there is a call to set up the writer for userLogFile. That should be within a privileged block and use the user's ugi.
