Steve Loughran commented on SPARK-6918:
---------------------------------------
Open a new one against Spark 1.5, as there may be a different cause
before that, look @ your client code for anything logged by
{{org.apache.spark.deploy.yarn.Client}} related to tokens; it may be something
went wrong client side and an HBase token could not be obtained.
> Secure HBase with Kerberos does not work over YARN
> --------------------------------------------------
>
> Key: SPARK-6918
> URL: https://issues.apache.org/jira/browse/SPARK-6918
> Project: Spark
> Issue Type: New Feature
> Components: YARN
> Affects Versions: 1.2.1, 1.3.0, 1.3.1
> Reporter: Dean Chen
> Assignee: Dean Chen
> Fix For: 1.4.0
>
>
> Attempts to access HBase from Spark executors will fail at the auth to the
> metastore with: _GSSException: No valid credentials provided (Mechanism
> level: Failed to find any Kerberos tgt)_
> This is because HBase Kerberos auth token is not send to the executor. Will
> need to have something similar to obtainTokensForNamenodes(used for HDFS) in
> yarn/Client.scala. Storm also needed something similar:
> https://github.com/apache/storm/pull/226
> I've created a patch for this that required an HBase dependency in the YARN
> module that we've been using successfully at eBay but am working on a version
> that does not require the HBase dependency by calling the class loader.
> Should be ready in a few days.
