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`.

Description

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

LOG.error("Read from {} on {}", table, server);

 

I think we can use WebUI to display these failures to make it easier for us to view this information

 

As shown in the figure above, we can directly see the Table and Regionserver where the error occurred
