Hello, everyone. This cluster has been running for a long time. Today pending tasks pile up too many tasks. Check the master log and find the following warn message. The master waits for the response of the bdes225 node after sending ClusterState. Until the master waits for the timeout.
I checked the log of bdes225 and found the following errors.
I have a doubt that I have not solved.
1、fatal error in thread [elasticsearch[bdes225-prd1][clusterService#updateTask][T#5]], exiting
After the log is printed, the Elastic search UncaughtExceptionHandler:: halt method is executed, but the JVM does not exit.
