COMET_COLUMNAR_SHUFFLE_ENABLED is the config Comet uses to decide if columnar shuffle should be used instead of native shuffle, if comet shuffle is enabled.

Currently if columnar shuffle is enabled, running Comet with TPCDS queries will get the error:
General execution error with reason org.apache.comet.CometNativeException: Fail to process Arrow array with reason C Data interface error: The external buffer at position 1 is null...
