> Key: STORM-1521
> URL: https://issues.apache.org/jira/browse/STORM-1521
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-hbase
> Affects Versions: 0.10.0, 0.9.5
> Reporter: Dan Bahir
> Assignee: Dan Bahir
>
> When logging in with a keytab, if the topology has more than one instance of
> an HBase bolt then the ticket will not be automatically renewed.
> Expected: The ticket will be automatically renewed and the bolt will be able
> to write to the database.
> Actual: The ticket is not renewed and the bolt loses access to HBase.
> Note when there is only one bolt with one executor is renews correctly.
> Exception in bolt is:
> 2015-12-18T09:41:13.862-0500 o.a.h.s.UserGroupInformation [ERROR]
> PriviledgedActionException as:u...@somewhere.com
> cause:javax.security.sasl.SaslException: GSS initiate failed [Caused by
> GSSException: No valid credentials provided (Mechanism level: Failed to find
> any
> Kerberos tgt)]
> 2015-12-18T09:41:13.862-0500 o.a.h.i.RpcClient [WARN] Exception encountered
> while connecting to the server : javax.security.sasl.SaslException: GSS
> initiate
> failed [Caused by GSSException: No valid credentials provided (Mechanism
> level:
> Failed to find any Kerberos tgt)]
> 2015-12-18T09:41:13.863-0500 o.a.h.i.RpcClient [ERROR] SASL authentication
> failed. The most likely cause is missing or invalid credentials. Consider
> 'kinit'.
