There was an HBase RPC connection from a client at the host (identified
by the IP:port you redacted). IIRC, the "read count=-1" is essentially
saying that the server tried to read from the socket and read no data
which means that the client has hung up. There were 33 other outstanding
HBase RPC connections after this connection was closed.
It has nothing to do with ZooKeeper.

All,
I am trying to understand the below message that I see in RS logs:
DEBUG org.apache.hadoop.hbase.ipc.RpcServer: RpcServer.listener,port=16020:
DISCONNECTING client x.x.x.x:xxxxx because read count=-1. Number of active
connections: 33
Is this disconnect because of ZooKeeper connections limit maxing out?
Is "Number of active connections: 33" message is just information?
Thank you,
