client.Client: failed to interact with node......ERROR

[Yair Even-Zohar <ya...@audiencescience.com>]

I'm running a 2 nodes cluster using hadoop and katta. Master on
qa-hadoop004 and slave on qa-hadoop005

 

When I'm running a search as root from a remote machine, all works well.

When I'm running the same given search as root from the same remote
machine using tomcat I'm getting the error below:

I'm pretty certain I pass the correct properties because the client
tries to contact the correct machines so something else is causing this
error and I have no clue what it is.

 

Thanks
