Subject [jira] [Created] (BEAM-2766) HadoopInputFormatIO should support Void/null key/values
Date Tue, 15 Aug 2017 02:23:00 GMT
Neville Li created BEAM-2766:
--------------------------------

             Summary: HadoopInputFormatIO should support Void/null key/values
                 Key: BEAM-2766
                 URL: https://issues.apache.org/jira/browse/BEAM-2766
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-extensions
    Affects Versions: 2.2.0
            Reporter: Neville Li
            Assignee: Reuven Lax
            Priority: Minor


Many Hadoop {{InputFormat}} implementations use {{Void}} as key/value type and generates null
values which causes {{NullPointerException}} in https://github.com/apache/beam/blob/master/sdks/java/io/hadoop/input-format/src/main/java/org/apache/beam/sdk/io/hadoop/inputformat/HadoopInputFormatIO.java#L714

{{HadoopInputFormatIO}} should ignore these and not clone them.
