Description

The Dr Elephant fetcher code requires the `yarn.resourcemanager.webapp.address` parameter, which is an optional configuration for Apache Hadoop. The parameter `yarn.resourcemanager.hostname` will automatically populate all `yarn.resourcemanager.*.address` parameters with default ports. dr-elephant should support this.

Research direction

Start with the Dr Elephant fetcher code that locates YARN ResourceManager and JobHistory using Hadoop configuration. Check how yarn.resourcemanager.webapp.address and yarn.resourcemanager.hostname are resolved, then verify that hostname-based default addresses work without the optional webapp address; add or update the relevant fetcher tests if present.
