Hello Tidy Bot, Alexey Serbin, Kudu Jenkins, Adar Dembo,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/15323
to look at the new patch set (#3).
Change subject: ksck: display quiecing-related info
......................................................................
ksck: display quiecing-related info
This patch adds quiescing-related info to ksck's "Tablet Server Summary"
section. Specifically, it displays the quiescing state, the number of
tablet leaders, and the number of active scanners[1].
If none of the tablet servers are quiescing, the quiescing state column
is omitted. If none of the tablet servers support the quiescing RPC, all
related columns are omitted.
I manually tested against a cluster that fully didn't support quiescing,
as well as one that partially supports quiescing[2].
The info is displayed by default with ksck, since the information may be
invaluable in debugging performance or workload skew. The info can be
ommitted by setting `--quiescing_info` to false.
[1] Sample output:

[2] Output of partial support for quiescing across the cluster yields "partial"
results; not the prettiest, but it's also not a scenario we expect often:
