Unable to get the Mixer Adapter walkthrough to work as described in the steps.

[vinayvenkat]

This is possibly a bug.

This is to do with the documentation to write a new mixer adapter specified at:

https://github.com/istio/istio/wiki/Mixer-Adapter-Walkthrough

What happened:

I followed the instructions to implement a new mixer adapter but got the following errors when I ran the mixer client command against the mixer server.

I got the following error:

What you expected to happen:

I expected the "out.txt" file to have the data that is called out in the mixer adapter example. However I don't see any output file being created. I'm not sure if I am missing anything. I followed all the steps in the example but don't see it working for me.

How to reproduce it:

Well followed the example and steps in: https://github.com/istio/istio/wiki/Mixer-Adapter-Walkthrough

@gargnupur Firstly thanks for this documentation. I followed it to the 'T' but don't seem to be getting the expected outputs. Would appreciate any help with this. Thanks!

My apologies but it looks i was looking for the file in the wrong location.

I was expecting the out.txt file to be in the mysampleadapter directory. But looks like it gets put into $ISTIO/istio/out.txt.

It might be a good idea to specify the full directory path or call this out in the document. Thanks once again for this great document. Maybe i'll send a pull request for these changes.
