Davies Liu 5ccecc078a [SPARK-15392][SQL] fix default value of size estimation of logical plan ... ## What changes were proposed in this pull request? We use autoBroadcastJoinThreshold + 1L as the default value of size estimation, that is not good in 2.0, because we will calculate the size based on size of schema, then the estimation could be less than autoBroadcastJoinThreshold if you have an SELECT on top of an DataFrame created from RDD. This PR change the default value to Long.MaxValue. ## How was this patch tested? Added regression tests.
