Josh Elser commented on ACCUMULO-3943:
--------------------------------------

I feel like there has to be something internal to HDFS already, no? [~cnauroth], do you know
of any tricks that we might be able to leverage from HDFS that would help us unravel when
different URIs ultimately point to the same HDFS instances (e.g. hdfs://localhost, hdfs://localhost:8020,
hdfs://fdqn:8020).

> I was helping a new user trying to use Accumulo. They managed to set up HDFS, running
on hdfs://localhost:8020.  But they didn't set it up with specific settings, and just used
the default port.  Accumulo worked initially, but would not allow a bulk import.
> During the bulk import process, the servers need to move the files into the accumulo
volumes, but keeping the volume the same. This makes the move efficient, since nothing is
copied between namespaces. In this case it refused the import because it could not find the
correct volume.
> Accumulo needs to be more nuanced when comparing hdfs://localhost:8020, and hdfs://localhost.
