配置信息：

Option	Description
Step name	Name of the step. Note: This name has to be unique in a single transformation.
Abort threshold	The threshold of number of rows after which to abort the transformations. E.g. If threshold is 0, the abort step will abort after seeing the first row. If threshold is 5, the abort step will abort after seeing the sixth row.
Abort message	The message to put in the log upon aborting. If not filled in a default message will be used.
Always log	Always log the rows processed by the Abort step. This allows the rows to be logged although the log level of the transformation would normally not do it. This way you can always see in the log which rows caused the transformation to abort.
