[jira] [Commented] (MAPREDUCE-4451) fairscheduler fail to init job
with kerberos authentication configured
[ https://issues.apache.org/jira/browse/MAPREDUCE-4451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13439832#comment-13439832 ]
Karthik Kambatla commented on MAPREDUCE-4451:
---------------------------------------------
Thanks for the patch, Eric.
I have the following minor comments:
- Use {{jobInitManagerThread}} instead of {{JobInitManagerThread}} (field name starting with lower case)
- In {{initJob()}}, we should probably use {{jobInitQueue.notify()}} instead of {{jobInitQueue.notifyAll()}}. It shouldn't be a problem in the current implementation. Should anyone use more job init threads later, only one of them should be notified.
- In {terminate()}:
-- Log a warning if the {{jobInitQueue}} is not empty.
-- Clear the {{jobInitQueue}}.
-- Not particular on this as it shouldn't affect functionality: we should probably add a {{jobInitManagerThread.join(TIMEOUT)}} in {{terminate()}} for proper clean up.

> When a job is submitted, fairscheduler calls JobTracker.initJob, which calls JobInProgress.generateAndStoreTokens to write security keys to hdfs. However, the operation is involved in the server side rpc call path, using UGI created by UserGroupInformation.createRemoteUser in rpc server, which have no tgt. This should be done with UGI used by JobTracker.
