I had a chat with [~vjasani] on Slack about this patch, bringing the conclusion 
here. I asked that this not be back-ported to branch-2.3 unless it proves 
necessary for some critical bug fixes. As there are no known bugs as of now, 
better to leave it at branch-2.

Thanks [~stack].

TestAdminShell is failing on master branch also, but the PR that I raised for 
this work had unit test +1 by QA bot multiple times. Let me dig in.

> Generic NamedQueue framework for recent in-memory history (refactor slowlog)
> 
>
> Key: HBASE-24718
> URL: https://issues.apache.org/jira/browse/HBASE-24718
> Project: HBase
>  Issue Type: Sub-task
>Reporter: Viraj Jasani
>Assignee: Viraj Jasani
>Priority: Major
> Fix For: 3.0.0-alpha-1, 2.4.0
>
>
> As per the discussion on parent jira, we should come up with named queue 
> (online ring buffer) to serve recent history for multiple use-cases like 
> slowlog, balancer decision, other region activities e.g flush, compaction, 
> split, merge etc.
> Since we already have slow/large rpc logs in ring buffer (HBASE-22978), as 
> part of this Jira, the proposal is to refactor slowlog provider to get 
> generic payload for ring buffer and based on event type (slow_log is the only 
> one for now), we can have separate internal in-memory queues.
> After this refactor, it should be relatively simpler to use the same 
> framework and create more cases like parent Jira (balancer decision in ring 
> buffer).
