             Summary: Ineffective null check in 
DataModelDesc#initComputedColumns()
                 Key: KYLIN-2702
                 URL: https://issues.apache.org/jira/browse/KYLIN-2702
             Project: Kylin
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


{code}
    private void initComputedColumns(Map<String, CCInfo> ccInfoMap) {
        if (ccInfoMap == null) {
            logger.error("cc info map is null");
        }
...
            CCInfo other = ccInfoMap.get(thisCCName);
{code}
Subsequent access to ccInfoMap may produce NPE.
