SequenceFileOutputFormat is coupled to WritableComparable and Writable

    Details

    • Type: Bug
    • Status: Closed
    • Priority: Blocker
    • Resolution: Fixed
    • Affects Version/s: 0.19.0
    • Fix Version/s: 0.19.0
    • Component/s: io
    • Labels:
      None
    • Release Note:
      Ensure that SequenceFileOutputFormat isn't tied to Writables and can be used with other Serialization frameworks.

      Description

      For some reason SequenceFileOutputFormat calls asSubclass() for OutputKeyClass and OutputValueClass. This throws a ClassCastException when using non-Writable types with the new Serialization framework.
