log-death testing on baremetal

I ran the accumulo continuous ingest test on my baremetal cluster. The verify map-reduce job was not completing.

It turns out that the home directory for the install user was full. This system was configured with a small space for /home, leaving most of the space in /var.

It would probably be better for hadoop, zookeeper, and accumulo to be configured to put logs in /var, and not the install user's account.
