Subject [jira] [Commented] (HBASE-19527) Make ExecutorService threads daemon=true.
Date Thu, 18 Jan 2018 19:25:00 GMT

stack commented on HBASE-19527:
-------------------------------

Got a +1 too up on RB from [~Apache9] (Need to fix an import).

Here is a case where this patch will help. TestRegionsOnMasterOptions.testRegionsOnAllServers
is one of our flakies. Looking at a hang, a Pv2 Worker thread is stuck trying to set region
status to CLOSE but the hbase:meta is not available – we are on our way out.

> Let me try this. ExecutorService runs OPENs, CLOSE, etc. If Server is going down, no
point in these threads sticking around (I think). Let me try this.
