[02/50] [abbrv] git commit: ACCUMULO-2787 Tune max open file
recommendation
ACCUMULO-2787 Tune max open file recommendation
Make the max files recommendation configurable to account for various
cluster sizes. Reduce the default from 64k to 32k because we shouldn't
need to compensate for running datanodes as the same user.
