Subject Re: java.lang.StackOverflowError

Hi,

Thanks for reporting the issue. Could you first try to upgrade to Flink 1.6.4? This might be a known issue fixed in a later bug fix release [1].

Also, are you sure you are using (unmodified) Flink 1.6.2? Stack traces somehow do not match with the 1.6.2 release tag in the repository, for example this one:

	at org.apache.flink.runtime.io.network.partition.consumer.RemoteInputChannel.notifyBufferAvailable(RemoteInputChannel.java:380) 

Doesn’t match the code [2]. (But first try to upgrade the Flink)
