Folks, Are there any dockerfiles or the like for setting up a local HA cluster with yarn using Docker (or something other than multiple VMs), using a custom build of Hadoop (ideally, straight out of the build tree) ?
Context: I’m working on changes for the ZKRMStateStore to alleviate a number of potential issues similar to YARN-5006, YARN-6825 and other cases where a change in application state causes a failure of the RM due to a too-large message to ZK. (In our particular instance, it was a Spark AM failing with a very large exception text.). I can repro similar problems in test cases, and validate their fixes – but I’d like an easy way to set up an actual running cluster on my laptop as well.
