Help needed - travis-ci : cannot find symbol: method cbfCode()

[Feng LI]

Hello guys,

Just wondering if someone can help me out with this very first pull request
- the travis-ci failed during Tests phase :
https://travis-ci.org/apache/flink/builds/494787984

The error seems unrelevant to my change though, do I need some trick to fix
it here?

Hi,

Thanks for reporting this.

I'm not entirely sure what happened with the build here - the master branch
is building without the error at the moment.
Also, your latest Travis run on the PR is passing:
https://travis-ci.org/apache/flink/builds/494952794
So, I would say, considering your PR it is ok to ignore that previous
failing build.

Nevertheless, I've pulled in Aljoscha (in CC) to keep an eye on this in
case it is some kind of instability with the TraversableSerializer.

Cheers,
Gordon
