Recently I found in the zookeeper log that there were too many client connections and it was hive that was establishing more and more connections.
I modified the max client connection property in zookeeper and that fixed the problem, temporarily. But the connections hive made to zookeeper were still growing. It seems that hive does not use a connection pool to reuse the connections. So how can I configure to reduce the connections? P.S. I am using Hive-0.12.0
