-------------------------------------
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.
