Subject [jira] [Commented] (HADOOP-15110) Objects are getting logged when we got exception from AutoRenewalThreadForUserCreds
Date Tue, 12 Dec 2017 14:58:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16287712#comment-16287712
] 

Steve Loughran commented on HADOOP-15110:
-----------------------------------------

It's the error string from kinit, " kinit: KDC can't fulfill requested option while renewing
credentials".

That's not Hadoop code. All that hadoop knows is that the exec() command failed with a -1
exception. 

Someone could list the command line sequence which had the problem, but otherwise: there is
nothing we can do.

FWIW, by the standard of Kerberos related error messages, this is a good one.

Downgrading to minor. If you are willing to provide the patch to list the command string,
that'd be great. Doing that might also help you track down the problem.

thanks
