METRON-1451: On Centos full dev, Metron Indexing shows up as stopped ## Contributor Comments **Root Cause** The python-requests module introduced a VendorAlias import machinery in v2.5.2 and caused the sys.modules to break. This issue was later fixed in v2.6.1 of python-requests (see [here](https://pypi.python.org/pypi/requests)). The solution is to use this version of python-requests, which fixed the issue. **Testing Done** On CentOS 6 full dev - Validated python-requests v2.6.1 is installed - Checked for the Metron Indexing service state to be up. - Checked ambari-agent.log and the error was not seen. On Ubuntu 14 full dev - Repeated the same steps as on CentOS 6 **Verification Steps** - Spin up full dev. - Verify Metron Indexing service is shown as up and running. ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
