Subject [jira] [Created] (HBASE-14629) Create replication zk node in postLogRoll instead of preLogRoll

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

             Summary: Create replication zk node in postLogRoll instead of preLogRoll
                 Key: HBASE-14629
                 URL: https://issues.apache.org/jira/browse/HBASE-14629
             Project: HBase
          Issue Type: Improvement
          Components: Replication
            Reporter: He Liangliang


Currently the hlog zk node is added before creating the log file, so it's possible to raise
FileNotFoundException if the server crash between these tow operations. Move this step after
file creating can avoid this exception (then FNFE will be certainly treated as an error).
If there is an crash after log creation before creating the zk node, the log will be replayed
and there should be no data loss either.
