strange json2sstable cast exception
Having run into a recurring compaction problem due to a corrupt sstable
(perceived row size was 13 petabytes or something), I sstable2json -x 'd
the key and am now trying to re-import the sstable without it. However,
I'm running into the following exception:
Importing 2882 keys...

be cast to org.apache.cassandra.db.SuperColumn

The CF is a SuperColumnFamily, if that's relevant.
1. What should I do about this problem?
2. (somewhat unrelated) Our usage of this SCF has moved away from requiring
"super"-ness. Aside from missing out on the potential for future seconary
indexes, are we suffering any sort of operational/performance hit from this
classification?

Forgot to mention node is: new install of 0.8.2, though data was streamed
over from nodes that have been upgraded over time from 0.7.

You should probably upgrade, it looks like you have a version that
doesn't support sstable2json with expiring columns.
