Nick Dimiduk updated HBASE-23994:
---------------------------------
Release Note:
<!-- markdown -->
The Canary tool now offers a WebUI when run in `region` mode (the default
mode). It is enabled by default, and by default, it binds to `0.0.0.0:16050`.
This can be overridden by setting `hbase.canary.info.bindAddress` and
`hbase.canary.info.port`. To disable entirely, set the port to `-1`.

> During the running of Canary, the table sniff failure information will be
> printed through the Log.

> I think we can use WebUI to display these failures to make it easier for us
