[jira] [Created] (KYLIN-2871) Ineffective null check in SegmentRange

Ted Yu created KYLIN-2871:
-----------------------------

             Summary: Ineffective null check in SegmentRange
                 Key: KYLIN-2871
                 URL: https://issues.apache.org/jira/browse/KYLIN-2871
             Project: Kylin
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


For Endpoint#getComparator() :
{code}
                    } else if (b.isMax) {
                        return a.isMax ? 0 : -1;
                    } else {
                        if (a == null || b == null)
                            throw new IllegalStateException();
{code}
The null check should be placed in the front.
