URL:
https://github.com/apache/carbondata/pull/3201
Modification:
1. SegmentPropertiesWrapper should check the column order for different segments
Because sort_columns modification can change the column order.
2. dictionaryColumnChunkIndex of blockExecutionInfo should keep projection order for compaction
3. if column drift happened, it should convert measure to dimension in RawResultIterator
