> 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 writing it to disk.
> How ever I have found bugs in the related code and the data load was failed after turning on this feature.
> This bug can be reproduced easily. I used the example from `TestLoadDataFrame` Line98.
> 1. create a dataframe (e.g. 320000 rows with 3 columns)
> 2. set carbon.is.sort.temp.file.compression.enabled=true in CarbonProperities
> 3. write the dataframe to a carbontable through dataframewriter
> Error messages are shown as below:
