Aleksey Yeschenko commented on CASSANDRA-6374:
----------------------------------------------
bq. Can this be fixed for 2.0.3 please? We need to upgrade our testing cluster
to 2.0.x but cannot because of this issue.
2.0.3 vote is being restarted, so yes, it will be in 2.0.3.
> AssertionError for rows with zero columns

> There Aaron Morton said that its caused by leaving rows with zero columns -
> that's exactly what we do in some CFs (using Thrift & Astyanax).
