Bug Description

The apache-hadoop-plugin charm calls HadoopBase.install, which calls configure_hosts_file, which sets the unit hostname based on the charm name:

https://github.com/juju-solutions/jujubigdata/blob/master/jujubigdata/handlers.py#L98

This is unwanted for subordinate charms like the plugin. We would rather this be set to the primary service on that unit (hive-0, pig-0, etc). Perhaps we should check for *plugin*, then set the hostname to the unit on the other side of the hadoop-plugin relation.

This isn't a show stopper, just annoying to be working on a unit named "plugin-x" and not know if you're on hive, pig, etc.
