--------------------------------------

             Summary: Fix problems detected by static code analysis
                 Key: RANGER-1991
                 URL: https://issues.apache.org/jira/browse/RANGER-1991
             Project: Ranger
          Issue Type: Bug
          Components: admin
    Affects Versions: 0.7.1
            Reporter: Zsombor Gegesy
            Assignee: Zsombor Gegesy


FindBugs/SpotBug detects a couple of problems with the code base:
 * Incorrect class casting - in XXServiceDef.equals
 * Unnecessary NPE checks - for variables which is known to be non-null (for example, because in other places a method is called on that object). In ServiceREST.java PublicAPIs.java, ServiceUtil.java and independently in XUserMgr.java

 * Collection.contains method call which is never true - in ServiceDBStore.validatePolicyItems for policyItem.getAccesses().contains("") - because getAccesses doesn't store String objects
 * Making public partially initialized objects in HadoopConfigHolder.initResourceMap()
 * Calling toString on array, which is not too readable
