-----------------------------------------------------------------
Since my last two comments, I increased my RF and started a rolling repair on
my nodes. This has caused this NPE to pop up on all the boxes over the last
couple of days as they process SSTables. Again, all the nodes are fresh 0.8.6
installs from a few days ago using the ComboAMI.

> NPE when writing SSTable generated via repair
> ---------------------------------------------

> Key: CASSANDRA-2863
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2863
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.8.1
> Reporter: Héctor Izquierdo
>
> A NPE is generated during repair when closing an sstable generated via
> SSTable build. It doesn't happen always. The node had been scrubbed and
> compacted before calling repair.
