---------------------------------
Summary: Analysis should check that join conditions' data types
are booleans
Key: SPARK-9292
URL: https://issues.apache.org/jira/browse/SPARK-9292
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Josh Rosen
Assignee: Josh Rosen
The following data frame query should fail analysis but instead fails at
runtime:
{code}
val df = Seq((1, 1)).toDF("a", "b")
df.join(df, df.col("a"))
{code}
This should fail with an AnalysisException because the column "A" is not a
boolean and thus cannot be used as a join condition.
This can be fixed by adding a new analysis rule which checks that the join
condition has BooleanType.
