Subject [jira] [Updated] (HBASE-14211) Add more rigorous integration tests of splits
Date Thu, 13 Aug 2015 16:13:46 GMT

     [ https://issues.apache.org/jira/browse/HBASE-14211?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Elliott Clark updated HBASE-14211:
----------------------------------
    Description: 
Add a chaos action that will turn down region size.
* Eventually this will cause regions to split a lot.
* It will need to have a min region size.

Add a chaos monkey action that will change split policy
* Change between Uniform and SplittingUpTo and back

Add chaos monkey action that will request splits of every region.
* When regions all reach the size a the exact same time the compactions add a lot of work.
* This simulates a very well distributed write pattern reaching the region size.

Add the ability to start with fewer regions than normal to ITBLL
