Eric Newton commented on ACCUMULO-1416:
---------------------------------------

The monitoring is nice; but it should probably not kill itself.

> With the removal of direct walogs, do we still need tservers monitoring the filesystem
and dying if things go wonky? Just had it happen and the death of the tserver didn't seem
necessary, especially with multiple disks.
