Description

6 out of the 8 streaming examples failed to run:

• Iteration & SessionWindowing & SocketWindowWordCount & WindowJoin failed to run due to java.lang.NoClassDefFoundError: org/apache/flink/streaming/examples/utils/ParameterTool
• MatrixVectorMul & TopSpeedWindowing failed to run due to: Caused by: java.lang.ClassNotFoundException: org.apache.flink.connector.datagen.source.GeneratorFunction

The NoClassDefFoundError with ParameterTool is introduced by FLINK-32558 Properly deprecate DataSet API - ASF JIRA (apache.org), and we'd better resolve FLINK-32820 ParameterTool is mistakenly marked as deprecated - ASF JIRA (apache.org) first before we come to a fix for this problem.
