https://github.com/apache/flink/pull/2564
New **gelly** tests failed with errors like:
> Caused by: java.io.IOException: Insufficient number of network buffers:
required 32, but only 3 available. The total number of network buffers is
currently set to 2048. You can increase this number by setting the
configuration key 'taskmanager.network.numberOfBuffers'.
Do you know what is causing this error? Should I update the code somehow?
