Hi, I've a cluster with Ambari 2.1.1 and HDP 2.3 stack. I've upgraded the Spark service manually to version 1.5.x from 1.3.
I want to remove the (now deprecated) configuration key "spark.yarn.applicationMaster.waitTries" and replace it with another key. Since the key is missing the delete button in the ambari-interface, how can I remove it? Do I have to do it manually in the db, or are there better ways? Regards, Eirik -- Eirik Thorsnes
