if the flow file contains "HdF5 file is missing Merging completed" I have to route to some processor using Route Text processor and if the flow files contains only "Merging completed" I have route to some other processor....how can I configure Rout

@sangee 

The "RouteText" [1] processor is used to route individual lines within a multi-line content FlowFile to different relationships (essentially splitting up a multi-line FlowFile).  What you are trying to accomplish can however be done using the "RouteOnContent" [2] processor.

Your sample shows content with two lines and only one of those lines containing the string "Merging completed".  So I assume the other FlowFIle's content will have only one line with "Merging complete"?

If so, the "RouteOnContent" can be configured as follows:

The dynamic property I added becomes a new relationship on the processor.  So any FlowFile where content matches exactly "Merging complete" will be sent to this relationship while all other FlowFiles will be routed to the pre-existing "unmatched" relationship.
