Tommy Stendahl commented on CASSANDRA-14419:
--------------------------------------------
I think the fix is similar as the fix for CASSANDRA-11960 so I have tried to
backport that pach to the 3.0 branch:
[cassandra-14419-30|https://github.com/tommystendahl/cassandra/commit/24a26abcd0d14f26e51616c8c23f11bd1ddb939a].
But the unit tests are broken, HintsCompressionTest failse with:
{code}
java.io.IOException: Digest mismatch exception
FSReadError in
