Jian He created HADOOP-14080:
--------------------------------
Summary: 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.
