Subject [jira] [Resolved] (HBASE-10572) Create an IntegrationTest for region replicas
Date Tue, 11 Mar 2014 18:42:00 GMT

     [ https://issues.apache.org/jira/browse/HBASE-10572?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Enis Soztutar resolved HBASE-10572.

      Resolution: Fixed
    Release Note: 
Adds an integration test for testing multi threaded gets with stale mode set in a table with
replicated regions. Chaos Monkey can be run to test the behavior where region servers and
masters are killed. 

Check the javadoc for IntegrationTestTimeBoundedRequestsWithRegionReplicas for how to run
the test. 
    Hadoop Flags: Reviewed

Committed to hbase-10070.

> We should add an integration test for testing reads from replicas with chaos monkey.

> I am thinking of a test which: 
>  - Creates a table with region replication
>  - Writes some data to a table with many regions per server. Ensures that the replicas
sees the data.
>  - Does time bounded gets (5 sec, etc) with timeline consistency. Failing to complete
the reads with a smaller latency will fail the test
>  - Runs Chaos Monkey to kill the region servers, master and runs balance. We do not want
other CM actions (flush, snapshot, etc)
