Hi,

Running sh scripts which runs on impala shell  from oozie workflow

WARNINGS: Row of size 175.18 MB could not be materialized in plan node with id 5. Increase the max_row_size query option (currently 512.00 KB) to process larger rows.

manual work performing on error getting set max_row_size=256mb;frequently.

recently changes some tables to parquet format is it the cause?

what can be the next solution?
