> When dfs.namenode.servicerpc-address is configured, NameNode launches an extra RPC server
to handle requests from non-client nodes. dfs.namenode.service.handler.count specifies the
number of threads for the server but the parameter is not documented anywhere.
> I found a mail for asking about the parameter. http://mail-archives.apache.org/mod_mbox/hadoop-user/201505.mbox/%3CE0D5A619-BDEA-44D2-81EB-C32B8464133D%40gmail.com%3E
