> ------------------------------------------------

> Key: SPARK-25740
> URL: https://issues.apache.org/jira/browse/SPARK-25740
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Yuming Wang
> Priority: Major
>
> How to reproduce:
> {code:sql}
> # spark-sql
> create table t1 (a int) stored as parquet;
> create table t2 (a int) stored as parquet;
> insert into table t1 values (1);
> insert into table t2 values (1);
> explain select * from t1, t2 where t1.a = t2.a;
> exit;
> spark-sql
> explain select * from t1, t2 where t1.a = t2.a;
> -- SortMergeJoin
> set spark.sql.statistics.fallBackToHdfs=true;
> explain select * from t1, t2 where t1.a = t2.a;
> -- SortMergeJoin, it should be BroadcastHashJoin
> exit;
> spark-sql
> set spark.sql.statistics.fallBackToHdfs=true;
> explain select * from t1, t2 where t1.a = t2.a;
> -- BroadcastHashJoin
> {code}
> We need {{LogicalPlanStats.invalidateStatsCache}}, but seems only we can do
> is invalidateAllCachedTables when execute set Command:
> {code}
> val isInvalidateAllCachedTablesKeys = Set(
> SQLConf.ENABLE_FALL_BACK_TO_HDFS_FOR_STATS.key,
> SQLConf.DEFAULT_SIZE_IN_BYTES.key
> )
> sparkSession.conf.set(key, value)
> if (isInvalidateAllCachedTablesKeys.contains(key)) {
> sparkSession.sessionState.catalog.invalidateAllCachedTables()
> }
> {code}
