Unexpected error occurred when query big data from parquet table

1

Hi team,

Currently I’m analyzing the data that stored under parquet file. So far dremio manage to pull out the data, unfortunately when querying bigger data by removing some of the where clause if throws Unexpected error occured

Could any of you care to suggest what would be the causes and what improvement i could do to avoid this?

Thanks and appreciate the output on this

Here I attaches the query profile if it helps to investigate the root cause
