[parisni]

Hi

looks livy 0.6.0 broke the session api

any will to make that compatible ?

[acroz]

Yeah, definitely. I'll look at it when I get a chance.

Do you know the specifics of what they've changed off hand?

Hi @parisni - we are using Livy 0.7.0 in the integration tests. Is there something we're not testing that is broken?

Hi
we are using livy 0.6.0 installed in a cloudera cluster with kerberos and it seems the proxyUser is not set.
The session json looks like this:
{"id":13,"name":null,"appId":null,"owner":null,"state":"starting","kind":"pyspark","appInfo":{"driverLogUrl":null,"sparkUiUrl":null},"log":[...]}

Hi @BjoernWaechter @acroz @parisni, I created a PR to resolve this issue and tested it on our cluster, now the code should work as expected.
