---------------------------------------
The test failure of "mixedModeReadColumnSubsetDigestCheck - org.apache.cassandra.distributed.upgrade.MixedModeReadTest" seems to be related. CASSANDRA-16415

> Basically when reading using certain column filters, the digest is different depending whether we read from sstable and memtable. This happens on {{trunk}} and {{cassandra-3.11}} branches. However it works properly on {{cassandra-3.0}} branch.
>
> I'm attaching a simple test for trunk to demonstrate what I mean.
>
> Please verify my test and my conclusions
