> For a customer, we found that they try to run hive on tez local mode tests, and due to
strict firewall rules and security policy, the DagClientServer struggles to start or respond
to connections (think about corporate laptops here). Instead of investigating the network-related
workarounds, let's find another way and decide if DAGAppMaster really needs this server. 
> LocalClient has an embedded [DAGAppMaster|https://github.com/apache/tez/blob/master/tez-dag/src/main/java/org/apache/tez/client/LocalClient.java#L65],
so at the first sight, it doesn't make sense to rely on the network environment in terms of
AM usage. Hopefully, AM can become more lightweight in the long term if we try to eliminate
pointless network usage.
