Koustav, I took your script (with GenerateFlowFile before it) and ran just fine (meaning the file is created and the processor does not hang). When I didn't have write permissions for the target folder, I got an error/bulletin telling me this. When I did have write permissions, it works fine.
However I should mention that if you want something to go to the PutFile (in your flow above), you will not get anything output (to the flow) with your current script. Instead you need to create/reuse a flow file and then use the session to transfer it. There is an example of how to do this on my blog: http://funnifi.blogspot.com/2016/03/executescript-json-to-json-revisited_14.html Regards, Matt On Wed, Aug 17, 2016 at 7:34 PM, koustav choudhuri <koustav1...@gmail.com> wrote: > Matt > > Thanks for Replying , but I am still struggling with ExecuteScript. > > > [image: Inline image 1] > > > in that ExecuteScript all I have is : > > Script - set to Python > Script Body : > from sys import argv > > filename = "nifi_output/nifi_test.txt" > target = open(filename, 'w') > target.write("My Name is Bond") > target.close() > > When I run this , Nifi hangs for some reason.
