Elasticsearch may have failed to start..tried multiple versions
According to the Elasticsearch Service Wrapper installation instructions:
Important: If you want to use service wrapper with elasticsearch 0.90 (and below), you need to switch to the 0.90 branch of this repository and then follow the installation instructions.
Looks like the master branch of the Elasticsearch Service Wrapper has been updated to address some class renaming that happened in the Elasticsearch 1.0.0-RC1 release (issue #4634). Please try using the 0.90 branch version of Elasticsearch wrapper, that should resolve your issue.
