When there's a inputRDD of a plan with 0 partitions, rule OptimizeSkewedJoin can hit NPE. The issue can be reproduced by below test: {code:java} withSQLConf(SQLConf.ADAPTIVE_EXECUTION_ENABLED.key -> "true", SQLConf.AUTO_BROADCASTJOIN_THRESHOLD.key -> "-1") { withTempView("t2") { // create DataFrame with 0 partition spark.createDataFrame(sparkContext.emptyRDD[Row], new StructType().add("b", IntegerType)) .createOrReplaceTempView("t2") // should run successfully without NPE runAdaptiveAndVerifyResult("SELECT * FROM testData2 t1 left semi join t2 ON t1.a=t2.b") } } {code} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
