Ramachandran created RANGER-3897:
------------------------------------

             Summary: Bug in RangerUserStore cache
                 Key: RANGER-3897
                 URL: https://issues.apache.org/jira/browse/RANGER-3897
             Project: Ranger
          Issue Type: Bug
          Components: Ranger
    Affects Versions: 3.0.0
            Reporter: Ramachandran


 

It seems Apache Ranger open source contains a bug where else block in the below code will not be called at all 

In the below code else block is a dead code
{code:java}

public RangerUserStore getLatestRangerUserStoreOrCached(XUserMgr xUserMgr, Long lastKnownUserStoreVersion, Long rangerUserStoreVersionInDB) throws Exception {
   RangerUserStore ret = null;

   if (lastKnownUserStoreVersion == null || !lastKnownUserStoreVersion.equals(rangerUserStoreVersionInDB)) {
      ret = getLatestRangerUserStore(xUserMgr, lastKnownUserStoreVersion, rangerUserStoreVersionInDB);
   } else if (lastKnownUserStoreVersion.equals(rangerUserStoreVersionInDB)) {
      ret = null;
   } else {
      ret = getRangerUserStore();
   }

   return ret;
} {code}
