when running the project ，after a period of time, connect hms sometimes breaks and does not reconnect (It may be a network issue, etc)

bug it not reconnect, I think this is a bit problematic

when i read code，i find it use new HiveMetaStoreClient(conf) to create IMetaStoreClient in MetastoreProvider#getRemoteMetastoreClient method . This way is not will reconnect, it should be replace RetryingMetaStoreClient.getProxy(conf)

some error message like

org.apache.thrift.transport.TTransportException Create breakpoint java.net.SocketException:Connection reset by peer:socket write error
at org.apache.thrift.transport.TIOStreamTransport.flush(TIOStreamTransport.java:161)~[libthrift-0.9.2.jar:0.9.2]
