Darla Baker resolved CASSANDRA-10170.
-------------------------------------
Resolution: Not A Problem
Following testing on the -jb- files we have concluded that the issue observed
was caused by corrupt -jb- tables that pre-existed the upgrade effort.
> Upgradesstables from 2.0.8 -jb- to 2.1.x -ka- some files are refusing to
> upgrade with java.lang.ClassCastException: null

> Key: CASSANDRA-10170
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10170
> Project: Cassandra
> Issue Type: Bug
> Reporter: Darla Baker
> Priority: Critical
>
> Not all -jb- tables throw this error, but I have a set of tables that will
> reproduce the error:

> This was seen in CASSANDRA-6738 (Not Reproduced), CASSANDRA-7112 (Fixed 2.1
> rc1) and CASSANDRA-7990 (Fixed 2.1.1). I decided to open a new Jira since
> this is being observed in a version where it should have been fixed and
> wasn't sure if perhaps one of the other Jiras should be reopened instead so
> I'll leave it to the experts.
> Since the sstables are sensitive, I can share the data privately as needed to
> reproduce and diagnose the issue.
