--------------------------------------
Summary: MR jobs are not working if started by a delegated user
Key: HBASE-9890
URL: https://issues.apache.org/jira/browse/HBASE-9890
Project: HBase
Issue Type: Bug
Components: security
Affects Versions: 0.96.0, 0.94.12, 0.98.0
Reporter: Matteo Bertozzi
Assignee: Matteo Bertozzi
Fix For: 0.98.0, 0.94.13, 0.96.1
Attachments: HBASE-9890-94-v0.patch
If Map-Reduce jobs are started with by a proxy user that has already the
delegation tokens, we get an exception on "obtain token" since the proxy user
doesn't have the kerberos auth.
For example:
* If we use oozie to execute RowCounter - oozie will get the tokens required
(HBASE_AUTH_TOKEN) and it will start the RowCounter. Once the RowCounter tries
to obtain the token, it will get an exception.
* If we use oozie to execute LoadIncrementalHFiles - oozie will get the tokens
required (HDFS_DELEGATION_TOKEN) and it will start the LoadIncrementalHFiles.
Once the LoadIncrementalHFiles tries to obtain the token, it will get an
exception.
