Description
**Dr Elephant does not work against YARN in HTTPS mode**
Configuration value of the property - `yarn.http.policy` which can have either of the values - `HTTP_ONLY / HTTPS_ONLY`, defines whether YARN is in HTTPS mode
1. [TezFetcher](https://github.com/linkedin/dr-elephant/blob/master/app/com/linkedin/drelephant/tez/fetchers/TezFetcher.java), works against App Timeline Server only in HTTP mode
2. [AnalyticJobGeneratorHadoop2](https://github.com/linkedin/dr-elephant/blob/master/app/com/linkedin/drelephant/analysis/AnalyticJobGeneratorHadoop2.java), works against Resource Manager UI only in HTTP mode

Check the yarn.http.policy values HTTP_ONLY and HTTPS_ONLY, then verify both integrations work under HTTPS mode as well as HTTP mode.
