Deegue updated SPARK-26630:
---------------------------
Affects Version/s: 2.4.1
2.4.0
> ClassCastException in TableReader while creating HadoopRDD
> ----------------------------------------------------------
>
> Key: SPARK-26630
> URL: https://issues.apache.org/jira/browse/SPARK-26630
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.4.0, 2.4.1, 3.0.0
> Reporter: Deegue
> Priority: Major
>
> This bug found in [link title|https://github.com/apache/spark/pull/23506] (PR
> #23506).
> It will throw ClassCastException when we use new input format (eg.
> `org.apache.hadoop.mapreduce.InputFormat`) to create HadoopRDD.So we need to
> use NewHadoopRDD to deal with this input format in TableReader.scala.
> Exception :
> {noformat}
> Caused by: java.lang.ClassCastException:
> org.apache.hadoop.mapreduce.lib.input.TextInputFormat cannot be cast to
