Subject [jira] [Created] (FLINK-8386) Scala API cannot create type information for Tuple interface
Date Mon, 08 Jan 2018 14:56:01 GMT
Timo Walther created FLINK-8386:
-----------------------------------

             Summary: Scala API cannot create type information for Tuple interface
                 Key: FLINK-8386
                 URL: https://issues.apache.org/jira/browse/FLINK-8386
             Project: Flink
          Issue Type: Bug
          Components: Type Serialization System
            Reporter: Timo Walther
            Priority: Minor


The Scala API type inference does not work with the {{org.apache.flink.api.java.tuple.Tuple}}
interface.

{code}
val ti: TypeInformation[_] = Types.of[Tuple]
{code}

Leads to:
{code}
Exception in thread "main" java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast
to [Lorg.apache.flink.api.common.typeinfo.TypeInformation;
	at org.apache.flink.table.examples.scala.WordCountTable$.main(WordCountTable.scala:47)
	at org.apache.flink.table.examples.scala.WordCountTable.main(WordCountTable.scala)
{code}
