Gin-zhj created CARBONDATA-558:
----------------------------------

             Summary: Load performance bad when use_kettle=false
                 Key: CARBONDATA-558
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-558
             Project: CarbonData
          Issue Type: Bug
            Reporter: Gin-zhj
            Assignee: Gin-zhj


When you import a data file, the measure column contains many empty strings， if use_kettle=false, the load performance has a sharp decline

I checked the logs of executor, many warnnings printed like below:
