--------------------------------------
Summary: Errors in FlushRunnable may leave threads hung

URL: https://issues.apache.org/jira/browse/CASSANDRA-7275
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Tyler Hobbs
Priority: Critical
Fix For: 2.0.8
In Memtable.FlushRunnable, the CountDownLatch will never be counted down if
there are errors, which results in hanging any threads that are waiting for the
flush to complete. For example, an error like this causes the problem:
