> 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.
