------------------------------------------------------------
[~apurtell] [~vjasani] [~bharathv] Thanks for the feedback. I'll remove the
metrics additions from the patches since this particular Jira concerns dumping
RITs into the logs. Do you have any suggestions on how often we should be
logging the RITs?
For the idea of adding a /rit endpoint in master, I've created a Jira
(https://issues.apache.org/jira/browse/HBASE-25469) to track it. Would love to
hear suggestions about what info to expose on the endpoint. If someone could
provide a servlet code example that would also be helpful, since I'm unfamiliar
with them in this code base. Thanks!

> We have metrics for number of RITs as well as number of RITs above a certain
> threshold, but we don't have any way of keeping track of the region hashes of
> those RITs. It would be beneficial to emit those region hashes as a metric,
> as well as log them, so that we don't accidentally lose this information for
> debugging the RIT at a later tiime.
