Duo Zhang commented on HBASE-21684:
-----------------------------------
When implementing HBASE-21671, I found that when shutting down a RS, my new
RegionReplicaReplicationEndpoint which is implemented with async client will
retry a lot of times and generate bunch of error logs. Then I notice that, the
problem is that, the async connection of the region server has been closed, but
the replication endpoint is still trying to replicate entries, and since for
region replica replication, we are replicating to the same cluster, so I just
reuse the async connection of the region server, which has already been closed.
The problem here is that, the StoppedRpcClientException is not a DNRIOE, so we
will keep retrying...
So I suggest that we change StoppedRpcClientException to extends DNRIOE, and
also for other places in hbase-client module, if we notice that the connection
is closed, just throw a DNRIOE out.
> Throw DNRIOE when connection or rpc client is closed
