Subject [jira] [Commented] (HBASE-10985) Decouple Split Transaction from Zookeeper
Date Thu, 24 Apr 2014 20:49:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10985?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13980263#comment-13980263

Ted Yu commented on HBASE-10985:
--------------------------------

{code}
+public interface SplitTransactionConsensus {
{code}
Please add annotation for audience.
{code}
+   * Finish off split transaction, transition the zknode
{code}
Consensus shouldn't be concerned with zk node, right ?
Same with znodeVersion below:
{code}
+      HRegion first, HRegion second, int znodeVersion, HRegion parent)
{code}
SplitTransactionConsensus shows, in various places, the dependence on zookeeper.

> As part of  HBASE-10296 SplitTransaction should be decoupled from Zookeeper. 
> This is an initial patch for review. At the moment the consensus provider  placed directly
to SplitTransaction to minimize affected code. In the ideal world it should be done in HServer.
