Ted Malaska commented on HBASE-15184:
-------------------------------------
ok I'm back from vacation I will try to finish a patch by mid week.
[~asrabkin] the problem is really simple. If a scan operation is the first
operation you are doing in your spark context (you haven't done a map or
foreach yet for example) Then the readers will not have the kerberos creds
applied yet and the scan will fail.
In the Zip file and in https://github.com/tmalaska/SparkOnHBase I solved this
in one way that required a extension of class that I shouldn't have extended.
Sense the creation of this Jira I had a vacation and on that vacation I figured
out how to implement this solution with out doing that extension that is a no
no.
I have a busy week, but I will try to get this jira in.
Thx

> I was using the HBase Spark Module at a client with Kerberos and I ran into
> an issue with the Scan.
> I made a fix for the client but we need to put it back into HBase. I will
> attach my solution, but it has a major problem. I had to over ride a
> protected class in spark. I will need help to decover a better approach
