Jian He updated HADOOP-14080:
-----------------------------
Target Version/s: 2.9.0
> UserGroupInformation#loginUserFromKeytab does not load hadoop tokens ?
> -----------------------------------------------------------------------
>
> Key: HADOOP-14080
> URL: https://issues.apache.org/jira/browse/HADOOP-14080
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Jian He
> Priority: Critical
>
> Found that UserGroupInformation#loginUserFromKeytab will not try to load
> hadoop tokens from HADOOP_TOKEN_FILE_LOCATION as loginUserFromSubject method
> does. I know typically, if you have the keytab, you probably won't need the
> token, but is this an expected behavior ?
> The problem with this is that suppose a long running app on YARN has its own
> keytabs, it does login via UserGroupInformation#loginUserFromKeytab, however,
> it will not load the hadoop tokens passed by YARN.
