The JIRA is to check in changes to address performance issues found during my performance testing as following: 1) When WALEdits belongs to a region which split/merged later incur extra waitUntilRegionOnline RPC call 2) Using a single shared connection for replaying archives better performance. Everytime creating a new connection, it incurs 4+ seconds to establish a connection to ZK. 3) other small modifications to mitigate excessive logging -- This message is automatically generated by JIRA.
