-----------------------------------

             Summary: The logical processing of streaming table has a bug in server, which will cause a NullPointerException.
                 Key: KYLIN-3060
                 URL: https://issues.apache.org/jira/browse/KYLIN-3060
             Project: Kylin
          Issue Type: Bug
          Components: streaming
            Reporter: peng.jianhua
            Assignee: peng.jianhua
         Attachments: create_non_interger_ID.png, edit_non_interger_ID.png

When you set the invalid parameter for creating or updating a streaming table, the client will show an error message dialog, refer to [^create_non_interger_ID.png] and [^edit_non_interger_ID.png].
I analyze the Kylin server log, there are some null pointer exceptions, then I analyze the StreamingController.java, whose logical processing of streaming table has a bug, which will cause a NullPointerException. 
So I repair it, you can check the patch.
