Summary: MTTR, Chaos, and ITBLL
Key: HBASE-20992
URL: https://issues.apache.org/jira/browse/HBASE-20992
Project: HBase
Issue Type: Sub-task
Components: integration tests, MTTR
Reporter: stack
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.
