----------------------------------------

             Summary: Local host-id may not be set when replaying commit log
                 Key: CASSANDRA-17525
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17525
             Project: Cassandra
          Issue Type: Bug
          Components: Local/Commit Log
            Reporter: Jon Meredith
            Assignee: Jon Meredith


The local host id is now used when replaying commit logs to prevent data loss 
when moving SSTables between nodes (CASSANDRA-16619).

The local host-id is assigned once on initial startup and persisted to the 
local.local table for use on subsequent startups - however it remains in the 
memtable/commitlog until the local table is eventually flushed.

If the node dies for any reason before the flush takes place, on the next 
restart a new host id will be allocated before the commit log is replayed and 
any sstables appearing in the commit log will be skipped incorrectly.
