[jira] [Resolved] (HBASE-14518) Give TestScanEarlyTermination the same treatment as 'HBASE-14378 Get TestAccessController* passing again...' -- up priority handlers

["stack (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-14518?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack resolved HBASE-14518.
---------------------------
       Resolution: Fixed
    Fix Version/s: 1.3.0
                   1.2.0
                   2.0.0

Pushed one-liner that sets priority handlers up to 10 from default 3.

Here is how the hang looks:

> Up the priority handlers. I see a bunch of clients trying to scan hbase:meta and then a bunch of occupied priority handlers -- though some seem open. Let me give this same treatment as was done for other big tests upping priority handlers to see if that helps.
