[jira] [Created] (HDFS-9762) NetworkTopologyWithNodeGroup.getNodeGroup() can loop infinitely for invalid 'loc' values

Kuhu Shukla created HDFS-9762:
---------------------------------

             Summary: NetworkTopologyWithNodeGroup.getNodeGroup() can loop infinitely for invalid 'loc' values
                 Key: HDFS-9762
                 URL: https://issues.apache.org/jira/browse/HDFS-9762
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.7.2
            Reporter: Kuhu Shukla
            Assignee: Kuhu Shukla
            Priority: Minor


Although the DatanodInfo/DataNodeDescriptor object tends to have a non-null, non-empty value for its network location, the getNodeGroup method does not handle the case if an empty or a null value is passed and can go on recursively causing StackOverflowError. This is an improvement to check for such a state and error out if the value is null and set the location to ROOT or empty string and if the original location is empty.
