Lin Wen resolved HAWQ-940.
--------------------------
Resolution: Fixed
> Kerberos Ticket Expired for LibYARN Operations
> ----------------------------------------------
>
> Key: HAWQ-940
> URL: https://issues.apache.org/jira/browse/HAWQ-940
> Project: Apache HAWQ
> Issue Type: Bug
> Components: libyarn
> Reporter: Lin Wen
> Assignee: Lin Wen
> Fix For: 2.0.1.0-incubating
>
>
> HAWQ's libhdfs3 and libyarn use a same kerberos keyfile.
> Whenever a hdfs operation is triggered, a function named login() is called,
> in login() function, this ticket is initialized by "kinit".
> But for libyarn, login() function is only called during the resource broker
> process starts. So if HAWQ starts up and there is no query for a long
> period(24 hours in kerberos's configure file, krb.conf), this ticket will
> expire, and HAWQ fails to register itself in Hadoop YARN.
