[jira] [Updated] (KYLIN-2702) Ineffective null check in DataModelDesc#initComputedColumns()

     [ https://issues.apache.org/jira/browse/KYLIN-2702?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ted Yu updated KYLIN-2702:
--------------------------
    Description: 
{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.

  was:
{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.
