The interpreter process exits normally, where the interpreter actively deletes the information in the cluster metadata. 2. The interpreter exits abnormally. zeppelin-server periodically checks if the interpreter is available. If it is not available, it will be set to offline. https://github.com/apache/zeppelin/blob/master/zeppelin-interpreter/src/main/java/org/apache/zeppelin/cluster/ClusterMonitor.java#L165 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
