Íñigo Goiri commented on HDFS-13274:
------------------------------------
RpcServerNumOpenConnections seems pretty high, can we confirm that those
connections are mainly because of renewLease() ops?
A potential solution is to make renewLease() more sync or having a different
pool for those so we don't affect regular ops.
