@Shubh18s : I have checked the code,
all the column names are stored without trim in SDK. But
long_string_columns table properties is having trim. column name has string
without trim but properties have string with trim. Hence the schema mismatch.
After this change, sort_columns and invertedIndexFor are affected.
As CarbonWriterBuilder.sortBy() is exposed to user, here also trim is not
there as per previous code. so add trim() here also. similar changes in
CarbonWriterBuilder.invertedIndexFor()
