> Currently HiveMetaStoreClient (or SessionHMSC) is connected to one Metastore server until
the connection is closed or there is a problem. I would like to introduce the concept of a
MetaStore client socket life time. The MS client will reconnect if the socket lifetime is
reached. This will help during rolling upgrade of Metastore.
> When there are multiple Metastore servers behind a VIP (load balancer), it is easy to
take one server out of rotation and wait for 10+ mins for all existing connections will die
down (if the lifetime is 5mins say) and the server can be updated.
