             Summary: When we cancel the Topic modification for 'Kafka Setting' of streaming table, the 'Cancel' operation will make a mistake.
                 Key: KYLIN-3061
                 URL: https://issues.apache.org/jira/browse/KYLIN-3061
             Project: Kylin
          Issue Type: Bug
          Components: Web 
            Reporter: peng.jianhua
            Assignee: peng.jianhua
         Attachments: cancel_is_not_right.png, edit_kafka_setting.png, edit_streaming_table.png

1. Choose one streaming table, choose the 'Streaming Cluster' tab, then click 'Edit' button, refer to [^edit_streaming_table.png]
2. The edit page will be opened, then you can edit the value of topic of 'Kafka Setting'. As long as you modify the ID, Host, Port value, the original value tag will follow changes, refer to [^edit_kafka_setting.png];
3. When you click 'cancel' button, you will find the old values have been changed to the new values, and if you click the 'submit' button, you will also find the values to be canceled will be submitted, refer to [^cancel_is_not_right.png]
But I think the correct way should be that 'cancel' button will not change any value.
I analyze the code and find out the bug of 'streamingConfig.js', the new broker is the same object as the old broker, we should clone the broker for the new broker, then it will be ok, so I repair it, please check the patch.
