Assignee: yucai
> No plan for BroadcastHint in some condition
> -------------------------------------------
>
> Key: SPARK-12275
> URL: https://issues.apache.org/jira/browse/SPARK-12275
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.6.0
> Reporter: yucai
> Assignee: yucai
>
> *Summary*
> No plan for BroadcastHint is generated in some condition.
> *Test Case*
> {code}
> val df1 = Seq((1, "1"), (2, "2")).toDF("key", "value")
> val parquetTempFile =
> "%s/SPARK-xxxx_%d.parquet".format(System.getProperty("java.io.tmpdir"),
> scala.util.Random.nextInt)
> df1.write.parquet(parquetTempFile)
> val pf1 = sqlContext.read.parquet(parquetTempFile)
> #1. df1.join(broadcast(pf1)).count()
> #2. broadcast(pf1).count()
> {code}
> *Result*
> It will trigger assertion in QueryPlanner.scala, like below:
> {code}
> scala> df1.join(broadcast(pf1)).count()
> java.lang.AssertionError: assertion failed: No plan for BroadcastHint
> +- Relation[key#6,value#7]
