             Summary: Unable to deserialize Coder in DataflowRunner
                 Key: BEAM-1624
                 URL: https://issues.apache.org/jira/browse/BEAM-1624
             Project: Beam
          Issue Type: Bug
          Components: runner-dataflow
            Reporter: Frances Perry
            Assignee: Davor Bonaci
            Priority: Blocker
             Fix For: 0.6.0


To repro, sync to head and run the LeaderBoard example with the Dataflow runner
Does not repro in 0.5.

Caused by: java.lang.RuntimeException: Unable to deserialize Coder: WindowedValue$FullWindowedValueCoder(KvCoder(BigQueryIO$ShardedKeyCoder(StringUtf8Coder),BigQueryIO$TableRowInfoCoder),IntervalWindow$IntervalWindowCoder). Check that a suitable constructor is defined.  See Coder for details.
