Description

As for dfs.namenode.handler.count we documented with below description
"The number of Namenode RPC server threads that listen to requests from clients. If dfs.namenode.servicerpc-address is not configured then Namenode RPC server threads listen to requests from all nodes."

however, for dfs.datanode.handler.count we documented with below description
"The number of server threads for the datanode."

 

The purpose of this Jira is to update the description for dfs.datanode.handler.count with
"The number of Datanode RPC server threads that listen to requests from client." to make it more readable to the users.
