14cbaeea009d5787dbf1b830a7e62964dad7a53a KUDU-3011 p7: add tool to quiesce server
Adds the following commands:
$ kudu tserver quiesce start <tserver_addr>
- sets the server to start quiescing
- optionally, if --error_if_not_fully_quiesced is true, the server
will respond with the number of leaders and active scanners, and if
either are non-zero, the tool will return an error
- users can orchestrate this to wait for a fully quiesced server. An
example of this is shown in RollingRestartITest.
$ kudu tserver quiesce stop <tserver_addr>
- sets the server to not be quiescing
Tests:
- Added some tests to exercise the quiescing tool in the context of a
rolling restart alongside the maintenance mode tooling.
- Also added some basic testing for the quiescing tooling alone.
