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.

Description

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)
