Suite of test scripts that a.) load a cluster with a verifiable dataset and b.)
do random kills of regionserver+datanodes in small cluster

Key: HBASE-2341
URL: https://issues.apache.org/jira/browse/HBASE-2341
Project: Hadoop HBase
Issue Type: Task
Reporter: stack
Fix For: 0.20.4, 0.21.0
We just filed hbase-2340 but discussion up on irc has it that we need something
more hardcore than pussy-footing inside a single jvm as hdfs-2340 does. The
point was made (tlipcon) that its hard to ensure real recovery working if all
is in the one JVM.
So, this issue is about scripts that can:
+ load a cluster with a dataset that we can 'verify' as in we can tell if it
has holes in it, if data has been lost.
+ script that does random kill of a random node on some random occasion
+ Script that can check cluster for data loss
All above should work while cluster is under load.
The above would not sit under junit.
This looks like a suite that we'd want to run up in ec2 using Andrew's scripts
and our donated aws credits.
{code}
16:12 < tlipcon> here's my goal: we have a 5 node cluster in the back room. I
want to run hbase on that at near full load for a week straight while some
process goes around screwing with it
16:12 < tlipcon> then I want to verify that I didn't lose a single edit over
that week
