Hi Bob, Do you know what the release schedule is for 2.0? We would like to use this in production within the next quarter-ish, so working on a non-certified release would not be ideal for us.
Would it make sense (or even be possible) to perform the configuration via the REST API? Ie. installing the ZKFC, adding the namenodes, and updating their configuration files to have everything configured correctly? Ansible would be able to also perform the appropriate shell commands.
