> The document says that the default value of ‘carbon.number.of.cores.while.loading’ is 2. But actually during data loading, carbondata use the the value of 'spark.executor.cores', which means that the description in document is incorrect.
> But this doesn't mean that the default value of 'carbon.number.of.cores.while.loading' is useless -- in compaction and sdk, carbondata still use this default value.
> In a word, we need to fix the implementation as well as the document, maybe some refactoring is needed.
