Donald Smith commented on CASSANDRA-6152:
-----------------------------------------
I have a hunch that when the column name is "" and the Memtable flushes to an
SSTable is when this bug bites. I notice it happens at about the same
iteration of the *for* loop in BugMain.java.
> Assertion error in 2.0.1 at
> db.ColumnSerializer.serialize(ColumnSerializer.java:56)
