>                 Key: HBASE-20992
>                 URL: https://issues.apache.org/jira/browse/HBASE-20992
>             Project: HBase
>          Issue Type: Sub-task
>          Components: integration tests, MTTR
>            Reporter: Michael Stack
>            Priority: Major
>
> I've been having trouble getting a sustained, large ITBLL run to complete over the last few days. I'm seeing a bunch of the below:
>  * A region splits or is moved
>  * Chaos kills the Master in the middle of the Split or Move Procedure after a Region has been offlined
>  * Master takes a while to come back whether because it is not started until a couple of minutes have passed and then there is some recovery to be done.
> So a region can be offline for minutes. Default we retry up to 16 times which ends up at about 2.5 minutes before we give up.
> So, I can up the retries when running larger tests but also, the region should come back online faster. 
> Let me hang ITBLL fixes/notes off here.
