Hello Alexey Serbin, Grant Henke, Hao Hao, I'd like you to do a code review. Please visit
http://gerrit.cloudera.org:8080/13510 to review the following change. Change subject: hms: allow for tooling to run without Kudu plugin ...................................................................... hms: allow for tooling to run without Kudu plugin Currently, whenever an HMS client successfully connects to the HMS, it checks the various HMS service configurations (e.g. that it is using the Kudu-HMS plugin), returning an error if any are misconfigured. This is important to make it much more obvious when the Kudu Master's HMS synchronization is misconfigured. It is still useful for other HMS clients (e.g. that used by the HMS tooling) to operate on an HMS instance that is not configured with the Kudu-HMS plugin et al. This patch removes the requirement by plumbing the option to the HMS client as a member of ThriftOptions. This was the most straightforward way to plumb this option from the HmsCatalog to the HmsClient, given the templating layered in between them for HA. Besides, we can use this option in the future if we ever want to verify the configuration of Thrift-based clients for other services (e.g. Sentry). To test, I added an HmsMode that starts the HMS without the Kudu-HMS plugin installed and used it in a couple of HMS tooling tests. I considered reusing the ENABLE_HIVE_METASTORE HmsMode, but opted not to since some tests are greatly simplified by ENABLE_HIVE_METASTORE having the Kudu-HMS plugin installed (e.g. restarting the HMS isn't required to enable the Kudu-HMS integration).
