             Summary: Append toMap to Map#filterKeys if the result of filter is concatinated with another Map
                 Key: SPARK-32871
                 URL: https://issues.apache.org/jira/browse/SPARK-32871
             Project: Spark
          Issue Type: Bug
          Components: Build
    Affects Versions: 3.1.0
            Reporter: Kousuke Saruta
            Assignee: Kousuke Saruta


As of Scala 2.13, Map#filterKeys return a MapView, not the original Map type.
This can cause compile error.
{code:java}
/sql/DataFrameReader.scala:279: type mismatch;
[error]  found   : Iterable[(String, String)]
[error]  required: java.util.Map[String,String]
[error] Error occurred in an application involving default arguments.
[error]       val dsOptions = new CaseInsensitiveStringMap(finalOptions.asJava) {code}
