[jira] [Commented] (HBASE-6088) Region splitting not happened for long time due to ZK exception while creating RS_ZK_SPLITTING node

stack commented on HBASE-6088:
--
The delete of the zk node should provide the sequence id so we don't delete a
znode we were not responsible for making.
This seems radical:
{code}
+} catch (KeeperException.NoNodeException nn) {
+ if (abort) {
+server.abort(Failed cleanup of + hri.getRegionNameAsString(), nn);
+ }
{code}
If we don't find our splitting node we abort?
Good test.

Failure in
org.apache.hadoop.hbase.regionserver.TestSplitTransactionOnCluster.testSplitBeforeSettingSplittingInZK
in 0.94 is due to the order of the newly added testcase.
In trunk its not a problem as the master restart related testcases are at the
beginning. Will provide an addendum for 0.94 sooner.

@Ted
bq.The second state should be RS_ZK_REGION_SPLIT.
As part of createNodeSplitting we transition from RS_ZK_REGION_SPLITTING to
RS_ZK_REGION_SPLITTING.
{code}
int transitionNodeSplitting(final ZooKeeperWatcher zkw, final HRegionInfo
parent,
final ServerName serverName, final int version) throws KeeperException,
IOException {
return ZKAssign.transitionNode(zkw, parent, serverName,
EventType.RS_ZK_REGION_SPLITTING, EventType.RS_ZK_REGION_SPLITTING,
version);
}
{code}
Thats why I have mentioned RS_ZK_REGION_SPLITTING as second state.
Pls correct me if wrong.

@Zhihong Yu
Thanks for review,
bq.The above two methods can remain static, right ?
removed static because we cannot override static methods(but subclass methods
hide superclass methods). The version of the hidden method that gets invoked
depends on whether it is invoked from the superclass or the subclass.
Correct me if I am wrong.

@Ted
Basically we changed the static to an instance method so that we can test the
split transaction. Infact though it was static the scope was private
previously.

---
While we start doing the split, there are two steps in zk node creation.
- Create the node
- Write the data RS_ZK_SPLITTING into it.
Now after both the steps are completed we make an journal entry.
Now if writing the data fails even on rollback we are not able to clean the
node as we don't know the current journal entry.
