Apache Spark reassigned SPARK-32621:
------------------------------------
Assignee: Apache Spark
> "path" option is added again to input paths during infer()
> ----------------------------------------------------------
>
> Key: SPARK-32621
> URL: https://issues.apache.org/jira/browse/SPARK-32621
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.4.6, 3.0.0, 3.0.1, 3.1.0
> Reporter: Terry Kim
> Assignee: Apache Spark
> Priority: Minor
>
> When "path" option is used when creating a DataFrame, it can cause issues
> during infer.
> {code:java}
> class TestFileFilter extends PathFilter {
> override def accept(path: Path): Boolean = path.getParent.getName != "p=2"
> }
> val path = "/tmp"
> val df = spark.range(2)
> df.write.json(path + "/p=1")
> df.write.json(path + "/p=2")
> val extraOptions = Map(
> "mapred.input.pathFilter.class" -> classOf[TestFileFilter].getName,
> "mapreduce.input.pathFilter.class" -> classOf[TestFileFilter].getName
> )
> // This works fine.
> assert(spark.read.options(extraOptions).json(path).count == 2)
> // The following with "path" option fails with the following:
> // assertion failed: Conflicting directory structures detected. Suspicious
> paths
> // file:/tmp
> // file:/tmp/p=1
> assert(spark.read.options(extraOptions).format("json").option("path",
> path).load.count() === 2)
> {code}
