Hello,
I have set spark.sql.autoBroadcastJoinThreshold=1GB and I am running the
spark job. However, my application is failing with:

When I am running with a limit 1 GB how can I hit the 8 GB limit? I made
sure in the Spark History Server as well by printing out the value of
spark.sql.autoBroadcastJoinThreshold that the value is correctly set and
explain plan also shows that it is trying to do a Broadcast Join. Any ideas?
