Keith Turner commented on HBASE-4821:
-------------------------------------
One other comment about random walk test vs functional test. Random walk will
also test adding splits in many different combination with other table
operations. For example a random walker may split, merge, update, split,
split, delete, etc. A functional test for add splits will not randomly mix
table operations like this. It will generally always test the same table
operation in the same order.

> Project: HBase
> Issue Type: Improvement
> Reporter: Mikhail Bautin
> Assignee: Mikhail Bautin
> Priority: Critical
>
> To properly verify that a particular version of HBase is good for production
> deployment we need a better way to do real cluster testing after incremental
> changes. Running unit tests is good, but we also need to deploy HBase to a
> cluster, run integration tests, load tests, Thrift server tests, kill some
> region servers, kill the master, and produce a report. All of this needs to
> happen in 20-30 minutes with minimal manual intervention. I think this way we
> can combine agile development with high stability of the codebase. I am
> envisioning a high-level framework written in a scripting language (e.g.
> Python) that would abstract external operations such as "deploy to test
> cluster", "kill a particular server", "run load test A", "run load test B"
> (we already have a few kinds of load tests implemented in Java, and we could
> write a Thrift load test in Python). This tool should also produce
> intermediate output, allowing to catch problems early and restart the test.
> No implementation has yet been done. Any ideas or suggestions are welcome.
