Jeffrey Zhong updated HBASE-8127:
---------------------------------
Attachment: reproduce-hang.patch
After applying the patch, run a clean build and then the following command:
{code}
mvn test -PlocalTests
-Dtest=TestMasterFailover#testMasterFailoverWithMockedRITOnDeadRS
{code}
You should be able to see the following error:
{code}
test timed out after 180000 milliseconds
{code}
> Region of a disabling or disabled table could be stucked in transition state
> when RS dies during Master initialization

> Key: HBASE-8127
> URL: https://issues.apache.org/jira/browse/HBASE-8127
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.94.5
> Reporter: Jeffrey Zhong
> Assignee: Jeffrey Zhong
> Attachments: reproduce-hang.patch

>
> The issue happens when a RS dies during a master starts up. After the RS
> reports open to the new master instance and dies immediately thereafter, the
> RITs of disabling tables(or disabled table) on the died RS will be in RIT
> state forever.
> I attached a patch to simulate the situation and you can run the following
> command to reproduce the issue:
> {code}mvn test -PlocalTests
> -Dtest=TestMasterFailover#testMasterFailoverWithMockedRITOnDeadRS{code}
> Basically, we skip regions of a dead server inside
> AM.processDeadServersAndRecoverLostRegions as the following code and relies
> on SSH to process those skipped regions:
> {code}
> for (Pair<HRegionInfo, Result> deadRegion : deadServer.getValue()) {
> nodes.remove(deadRegion.getFirst().getEncodedName());
> }
> {code}
> While in SSH, we skip regions of disabling(or disabled table) again by
> function processDeadRegion. Finally comes to the issue that RITs of
> disabling(or disabled table) stuck there forever.
