Sean Busbey commented on HBASE-21838:
-------------------------------------
Can we get a follow-on jira that adds some docs for this in the ref guide? with
an example of enabling it, what it looks like when things are fine, when
they're not, etc?
> Create a special ReplicationEndpoint just for verifying the WAL entries are
> fine

> This is a missing part in our ITBLL. We can config a dummy replication
> endpoint which replicates nothing but only reads and verifies that all the
> wal files are readable and the entries are all fine.
> With this I think it will be much easier to catch the problem in the parent
> issue.
