There is a known issue where the Service Monitor in Cloudera Manager opens
connections to ZooKeeper but due to a bug, doesn't close the connection.
Your options are:
1. Disable HBase RegionServer Health Canary by changing the "HBase Region
Health Canary" enabled flag in the HBase service configuration to false.
This is the easiest solution.
2. Upgrade to a version of CM that includes the fix (4.8.5, 5.0.5, 5.1.4,
5.2.1, 5.3.0)
3. Frequently restart the service monitor (disruptive and not recommended)
BTW please try to move away from Beta versions. Our latest relase is v5.3.0
and it is highly recommended that you migrate to it
