Description

I created a 100-column table of UUIDs, then inserted rows that didn't populate every column. When I insert 8 values, the insertion completes successfully. When I insert 9 values, the request fails with an AssertionError:

ERROR [SharedPool-Worker-2] 2015-08-25 12:46:27,839 Message.java:611 - Unexpected exception during request; channel = [id: 0xf0ea910e, /127.0.0.1:57948 => /127.0.0.1:9042]
