> Flink cannot be built for Hadoop 2.9.0 which was released on Nov. 17th, 2017.
> When running 
> {code}
> mvn clean install -DskipTests -Dhadoop.version=2.9.0
> {code}
> Maven fails with the following error:
> {code}
> [ERROR] /Users/fhueske/Development/flink/flink-yarn/src/test/java/org/apache/flink/yarn/UtilsTest.java:[239,16]
org.apache.flink.yarn.UtilsTest.TestingContainer is not abstract and does not override abstract
method setExecutionType(org.apache.hadoop.yarn.api.records.ExecutionType) in org.apache.hadoop.yarn.api.records.Container
> {code}
> The problem is caused, because Hadoop 2.9.0 extended the {{Container}} interface with
a getter ({{getExecutionType()}}) and a setter method ({{setExecutionType()}}) and adds a
class dependency on {{ExecutionType}}.
> Flink's {{UtilsTest}} class defines a class {{TestingContainer}} that implements the
{{Container}} interface.
> We cannot simply update the implementation of {{TestingContainer}} because previous versions
of Hadoop do not provide {{ExecutionType}}.
