> Currently, the TimeoutException that is thrown on broadcast joins doesn't give any clues to user how to resolve the issue. Need to provide such help to users by pointing out two config parameters: *spark.sql.broadcastTimeout* and *spark.sql.autoBroadcastJoinThreshold*.
> The ticket aims to handle the TimeoutException there: https://github.com/apache/spark/blob/b7a036b75b8a1d287ac014b85e90d555753064c9/sql/core/src/main/scala/org/apache/spark/sql/execution/exchange/BroadcastExchangeExec.scala#L143
