spark-sql --master yarn --queue default --driver-memory 2g --driver-cores 2 --executor-memory 6g --executor-cores 2 --num-executors 4 --conf spark.driver.cores=2 --conf spark.eventLog.enabled=false --conf spark.sql.broadcastTimeout=600000 --conf spark.dynamicAllocation.enabled=false --conf spark.sql.adaptive.enabled=true --conf spark.serializer=org.apache.spark.serializer.KryoSerializer --conf spark.blacklist.enabled=true --conf spark.sql.hive.convertMetastoreParquet=false --conf spark.sql.autoBroadcastJoinThreshold=1G

 分析原因：

因为spark.sql.adaptive.enabled=true开启自动调优，spark.sql.autoBroadcastJoinThreshold=2G

会开启autoBroadcast，spark.sql.autoBroadcastJoinThreshold=-1关闭就可以了。

如果资源充足那就需要增加driver内存和调整spark.sql.autoBroadcastJoinThreshold内存，可以根据需要开启spark.broadcast.compress=true。

在使用多表关联的时候慎重开启spark.sql.adaptive.enabled=true。
