What is the cause of RegionServer downtime? I believe many inexperienced people don't know what to do about it. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

HBase cluster may experience RegionServer downtime when it is running, for the following reasons:

Network disconnected, heartbeat transmission failed, trying to connect to another zookeeper server. (zookeeper will try to connect to all other servers.) the network is restored and the connection is successful, but the session has expired, so the zookeeper client is closed.

Of course, HMaster will also be interrupted by the expired failure information of Zookeeper.
