Today we upgraded the cluster to recent Elasticsearch 1.4 branch, after
upgrade we are seeing this message in the master logs.
[2015-04-28 14:40:47,942][ERROR][marvel.agent ] [els-master]
Exporter [es_exporter] has thrown an exception:

I tried to install the latest version of marvel, but still the same
issue. I wonder if someone else is facing it or we have something
special going on in our setup.
