Duo Zhang updated HBASE-27967:
------------------------------

(was: 3.0.0-beta-2)
> introduce a ConnectionLimitHandler to limit the number of concurrent
> connections to the Server
> ----------------------------------------------------------------------------------------------
>
> Key: HBASE-27967
> URL: https://issues.apache.org/jira/browse/HBASE-27967
> Project: HBase
> Issue Type: New Feature
> Components: IPC/RPC
> Affects Versions: 3.0.0-alpha-4
> Reporter: ruanhui
> Priority: Minor
> Fix For: 4.0.0-alpha-1
>
>
> The unreasonable retries of the client cause the hbase server to fail to
> accept and create new connections, and thus hang up. We can consider
> introducing a ConnectionLimitHandler similar to Cassandra in our
> NettyRpcServer to protect the hbase servers.
