there are three kafka brokers , in the cluster but one of the broker is not available in the zookeeper . In the cluster there are two role groups one is default role group where there are two kafka brokers and other one with other name with one broker available . What could be issue that lead to unavailibilty of one kafka broker in zookeeper.

There are very old files under /spark2-history and because of this spark2 web ui is getting stuck on loading history , I have gone thorough some of the documentations where it is mentioned setting below property will solve the issue .Please find below property : spark.history.fs.cleaner.enabled spark.history.fs.cleaner.maxAge spark.history.fs.cleaner.interval would these property be same for the spark2 as well ? also I do not see these property already existing , and in spark docs default property is mentioned there . https://spark.apache.org/docs/latest/monitoring.html
