--------------------------------------

             Summary: Data load failed when using compressed sort temp file
                 Key: CARBONDATA-1839
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-1839
             Project: CarbonData
          Issue Type: Bug
            Reporter: xuchuanyin
            Assignee: xuchuanyin


Carbondata provide an option to optimize data load process by compressing the intermediate sort temp files.

The option is `carbon.is.sort.temp.file.compression.enabled` and its default value is `false`. In some disk tense scenario, user can turn on this feature by setting the option `true`, it will compress the file content before write it to disk.

How ever I have found bugs in the related code and the data load is failed after turn on this feature.

Error messages are shown as below:
