Github user iraghumitra commented on the issue: https://github.com/apache/metron/pull/620 @nickwallen metron-alerts package.json already mentions that it is Apache 2.0 licensed. The license-checker tool reports the license of private repos as 'UNLICENSED' hence the issue. You can confirm this behavior of license-checker [here](https://github.com/davglass/license-checker/pull/108). I changed the license name in package.json file from 'Apache 2.0' to 'Apache-2.0' to make it consistent with other packages.
