Description

In ServerRpcConnection.saslReadAndProcess, if an uncaught exception happens while initialising HBaseSaslRpcServer, the same gets swallowed inside netty and never explicitly logged on RegionServer logs. With the introduction of pluggable sasl server providers by HBASE-23347, this situation can become more frequent with the addition of custom providers, if those cause HBaseSaslRpcServer to fail, that should be logged in ServerRpcConnection.saslReadAndProces.
