Description
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.
