I think you can cinfigure ZooKeeper to do that.
The problem in that test was that the Kafka server has an initial timeout
when trying to connect to ZooKeeper. Here, ZooKeeper is an embedded
mini-cluster-zookeeper for tests. Apparently either that mini cluster did not
start properly, or the build was accidentally very slow (it happens in these
shared VM environments) so that the timeout triggered.

> Project: Flink
> Issue Type: New Feature

> Add a AverageAccumulator for Flink-Accumulator to calculate the average of
> values.
> The feature is like Storm-MultiReducedMetric.
> Feature in detail:
> 1.This class is named AverageAccumulator(any suggestion? I`m not good at
> English name) and implements SimpleAccumulator.
> 2.This class support long, integer and double input.
> 3.This class will return a double value as the average when the method
> getLocalValue() called.
> 4.Member method description:
> * add():
> A variety of add() method to support different inputs(e.g. Double, double,
> Long, long, Integer, int).
> It will add the input value and make the count + 1 each time.
> * public Double getLocalValue():
> To return the sum of value dividing count as average and the result will be
> "double".
> * public void resetLocal():
> To reset the value and count.
> It won`t be called automatically and it will be better to call this every
> time the getLocalValue() method called.
> * public void merge(Accumulator<Double, Double> other):
> To merge another accumulator(only support AverageAccumulator).
> * public AverageAccumulator clone():
> To return the whole current AverageAccumulator class.
