Doesn't HDFS use /tmp by default to store its data?
You may want to update your ${HADOOP_HOME}/conf/hdfs-site.xml file to
specify a different location.

I would probably design the experiment to test different cluster sizes
as completely independent. That means, taking the entire thing down
and back up again (possibly even rebooting the boxes, and/or
re-initializing the cluster at the new size). I'd also do several runs
while it is up at a

I think an important take-away here (so far) is that you can't just
use "doctor" as a role... because that doesn't encapsulate all the
security considerations. Doctor X doesn't get to see patient Y's data,
unless X is Y's doctor, or Y has signed a release for him/her to see
it. So, "doctorOf" is an
You can still index a 1GB file... you just shouldn't try to push it
all in in a single mutation, nor should you try to store it using a
scheme that uses large keys.
You can even still store the whole raw file in Accumulo, particularly
if you chunk it up across multiple entries, but you may have to
I believe Accumulo can work across data centers, if the underlying DFS
span data centers. I also believe the latency tolerance is
configurable, and matters for servers holding locks in Zookeeper and
heartbeat messages to the Master. I'm not sure what the defaults for
these are, though.

If you're going to only do aggregation at the scan scope, you'd
probably want to make sure you don't have the versioning iterator
turned on for minc and majc scopes. Otherwise, you're scans may look
different over time between initial ingest and later, when the data
has been compacted on disk.

I don't know that ACCUMULO-826 should be fixed before release, as I'm
not sure there's a good fix without changing the API, and these issues
may occur in several places in the MapReduce API.

That feature (ACCUMULO-489) had some fundamental flaws (ACCUMULO-826).
One of the arguments made when rolling that back, was that the feature
was not introduced in a minor release (it didn't appear in 1.4.0), so
it wasn't part of the "1.4" contract. I apologize for the
inconvenience this has caused
