sunjincheng created FLINK-11971:
-----------------------------------
Summary: The classpath is missing the `flink-shaded-hadoop2-uber-2.8.3-1.8.0.jar` JAR during the end-to-end test.
Key: FLINK-11971
URL:
https://issues.apache.org/jira/browse/FLINK-11971 Project: Flink
Issue Type: Bug
Components: Tests
Affects Versions: 1.8.0, 1.9.0
Reporter: sunjincheng
Since the difference between 1.8.0 and 1.7.x is that 1.8.x does not put the `hadoop-shaded` JAR integrated into the dist. It will cause an error when the end-to-end test cannot be found with `Hadoop` Related classes, such as: `java.lang.NoClassDefFoundError: Lorg/apache/hadoop/fs/FileSystem`. So we need to improve the end-to-end test script, or explicitly stated in the README, i.e. end-to-end test need to add `flink-shaded-hadoop2-uber-XXXX.jar` to the classpath. So, we will get the exception something like:
{code:java}

So, I think we can import the test script or import the README.
What do you think?
