> HBase ThriftServer will cache Zookeeper connection in memory using org.apache.hadoop.hbase.util.ConnectionCache.
This class has a mechanism called chore to clean up connections idle for too long(default
is 10 min). But method timedOut for testing whether idle exceed for maxIdleTime always return
false which leads to never release the Zookeeper connection. If we send request to ThriftServer
every maxIdleTime then ThriftServer will keep thousands of Zookeeper Connection soon.
