issues with NiFi tutorial

[#1]

i am following this tutorial

http://hortonworks.com/hadoop-tutorial/how-to-refine-and-visualize-server-log-data/

step 3: import the flow gives a download link for the template but if i click that link it doesn't download ,it opens a page with some xml code.

how can i download this template?

also this tutorial is using a predefined workflow, is there a tutorial that teaches how to build this workflow ?

Hi @Sami Ahmad,

It looks as if the download link is to the actual NiFi template you'll need for the tutorial (called ServerLogGenerator.xml). NiFi templates are xml based. You can actually save that file locally on your machine (just do a save as through the browser) and follow the instructions to upload the template you saved locally into NiFi.

I hope this helps!

P.S. Here's another tutorial where you can learn NiFi essentials: http://hortonworks.com/hadoop-tutorial/learning-ropes-apache-nifi/#section_4

Instead of left clicking on the link in step three, right click and select "Save Link As..." option to save the xml template so it can be imported in to your NiFi.

The dataflow template will show you all the components needed for this workflow. I believe the intent of this tutorial was not to teach users how to use the NiFi UI, but rather how to use a combination of specific NiFi components to build accomplish a particular workflow.

Using the NIFi UI dataflow tools you can recreate the workflow as a UI dataflow building exercise.

Thanks,

Matt
