Till Rohrmann updated FLINK-9860:
---------------------------------
Description:
The Hadoop-free Wordcount end-to-end test fails with the following exception:
{code}
ERROR org.apache.flink.shaded.netty4.io.netty.util.ResourceLeakDetector - LEAK: ByteBuf.release() was not called before it's garbage-collected. See http://netty.io/wiki/reference-counted-objects.html for more information.
