Summary: Running TestZKRMStateStorePerf with real zookeeper cluster throws NPE Key: YARN-4880 URL: https://issues.apache.org/jira/browse/YARN-4880 Project: Hadoop YARN Issue Type: Bug Reporter: Rohith Sharma K S While going throw TestZKRMStateStorePerf class , found that we are not initializing variable {{TestingServer curatorTestingServer}} if real zookeeper cluster are passed to utility. But down the line , this variables are used which causes NPE I tested by passing program arguments which result in NPE {noformat} SLF4J: Class path contains multiple SLF4J bindings.
