------------------------------------
Summary: Flink cannot be built for Hadoop 2.9.0
Key: FLINK-8177
URL: https://issues.apache.org/jira/browse/FLINK-8177
Project: Flink
Issue Type: Bug
Components: YARN
Affects Versions: 1.4.0, 1.5.0
Reporter: Fabian Hueske
Priority: Critical
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}}.
