Parquet taking more memory than sequenceFile.

My data file in SequenceFile format occupied 140gb storage. After converting it to Parquet format the storage increased to 150gb. I am curious why this happened and can this happen. Help!


The query I used is 


Create table table_name (
) stored as parquet tblproperties("parquet.compress"="ZLIB") as select*from original_table;
