[jira] [Commented] (CASSANDRA-10170) Upgradesstables from 2.0.8
-jb- to 2.1.x -ka- some files are refusing to upgrade with
java.lang.ClassCastException: null
[ https://issues.apache.org/jira/browse/CASSANDRA-10170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14711478#comment-14711478 ]
Darla Baker commented on CASSANDRA-10170:
-----------------------------------------
I loaded the -jb- data sstable into a fresh install of c* 2.0.10 using sstableloader and it loaded fine. But when running select * from <ks>.<table> in cqlsh I get the following stack trace:

> 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.
