Subject [jira] [Updated] (HBASE-18610) Provide capability to activate chaos monkey
Date Fri, 25 Aug 2017 23:59:00 GMT

     [ https://issues.apache.org/jira/browse/HBASE-18610?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ted Yu updated HBASE-18610:
---------------------------
    Attachment: 18610.v6.txt

Patch v6 removes the call to Stop() since in the current form of ChaosMonkeyRunner, there
is no way to retrieve the spawned monkey runner.

Please provide more detail on the crash when monkey option is passed.

I verified that ChaosMonkeyRunner received the passed arguments by adding prints in main()
method.
Here is sample output:
{code}

> Currently load-client runs against a cluster where region servers are stable.
> We need to introduce chaos monkey so that wider coverage for read path is exercised.
