[SPARK-8982][Core] Worker hostnames not showing in Master web ui when
launched with start-slaves.sh
If a "--host" argument is not provided to Worker, WorkerArguments uses
Utils.localHostName to find the host name. SPARK-6440 changed the functionality
of Utils.localHostName to retrieve the local IP address instead of host name.
Since start-slave.sh does not provide the "--host" argument, clusters
started with start-slaves.sh now show IP addresses instead of hostnames in the
Master web UI. This is inconvenient when starting and debugging small clusters.
A simple fix would be to find the local machine's hostname in
start-slave.sh and pass it as the "--host" argument. I'm not sure if this fix
is appropriate for general use, so I'm interested in feedback.
This contribution is my original work and I license the work to the project
