threads hung
Tyler Hobbs created CASSANDRA-7275:
--------------------------------------
Summary: Errors in FlushRunnable may leave threads hung
Key: CASSANDRA-7275
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:
