Kenneth Knowles commented on BEAM-1624:
---------------------------------------
It hasn't been reproduced, so I am closing it. I will follow up to make sure
our ITs are sufficient.
> 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: Kenneth Knowles
> Priority: Blocker
> Fix For: Not applicable
>
>
> 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.
