@Eugene
In your patches, You only deale with the root/meta regionserver. If a normal regionserver registers laterly.
Master will process it as a dead one. Some regions in the later one will be opened twice.

[jira] [Commented] (HBASE-3933) Hmaster throw NullPointerException

Ted Yu commented on HBASE-3933:
-------------------------------
The changes in HMaster copied some existing code. We can add the new check to the existing if statement so that we don't copy the code in the if block.
For the changes in waitForRegionServers(), I guess the rationale is to prevent the region server which carried .ROOT. to checkin after that point. If so, we should still let other region servers to continue checking in.

gaojinchao commented on HBASE-3933:
-----------------------------------
I study the TRUNK. It has fixed. So we can close this issue.
Trunk code:
// Wait for region servers to report in.
this.serverManager.waitForRegionServers(status);
// Check zk for regionservers that are up but didn't register
for (ServerName sn: this.regionServerTracker.getOnlineServers()) {
if (!this.serverManager.isServerOnline(sn)) {
// Not registered; add it.
LOG.info("Registering server found up in zk: " + sn);
this.serverManager.recordNewServer(sn, HServerLoad.EMPTY_HSERVERLOAD);
}

------------------------------
@Gao I'm with Ted that you should not duplicate code. On going to 9seconds from 4.5, do you think your change generally applicable? Everyone will now have to wait at least nine seconds before startup proceeds. Or is it that you have a cluster with lots of regionservers? Can you not just up the configuration for how long to wait on new regionservers to check in? Also, can you say more on why you block regionservers coming in and actually tell them shutdown. Thats a pretty radical change. Thanks.

Hi Ted.
Hlog will be split after waitForRegionServers. So I prevent all region server to chechin and stop these region server after that point.

-----------------------------------
Please review it and give some suggestion. If the solution is ok, I will test it. Thanks.
Because region server interval is 3s, So I think hbase.master.wait.on.regionservers.timeout should be 9s.

-----------------------------------
Hi all. I have a new idea for this issue. why don't we get the regionserver list from zk when it is failover?
we can avoid this case that the hlog is splited but region server is servering.
