Excellent.
As long as you didn't have anything you needed to preserve, deleting the
data and re-init'ing is definitely the easiest. I do quite a bit of work
on OSX again these days -- you shouldn't have too many issues :)

Firstly, thanks Josh. I forgot I reinstalled Zookeeper--it had been a
casualty of my OSX upgrade--and neglected to set the data path. I did
that, but Accumlo still wouldn't start. I then deleted the /ACCUMULO
directory in HDFS and did a re-init. That fixed it. Accumulo appears
to be running and Zookeeper is listing something that looks right.
I think I'll declare victory--well see.

Alright, well that's your problem! Your ZooKeeper is empty. Accumulo
uses the information it places in ZooKeeper to bootstrap and find
the data in HDFS.
Are you sure you configured the ZooKeeper dataDir to be something
other than /tmp? In $ZOOKEEPER_HOME/conf/zoo.cfg, something like:
dataDir=/var/lib/zookeeper/

See what kind of results come from `ls /accumulo` and `ls
/accumulo/instances` in the ZooKeeper shell
($ZOOKEEPER_HOME/bin/zkCli.sh)____. '/accumulo' should be
non-empty,
and you should see the instance name you provided when running
`accumulo init` inside '/accumulo/instances'

All,
Suddenly, Accumulo will no longer start. Log files are not
helpful. Is
there a way to troubleshoot this?
The back story is I upgraded from OSX 10.7 to 10.9.
Everything was
working with 10.7. But with 10.9 Accumulo began to
complain of
insufficient file limits and recommended setting
maxfiles to 65536,
which I did.
Hadoop starts -- version 2.3.0
Zookeeper starts -- version 3.4.6
Java -- version 1.7.55
I've included part of a log file just in case.
Thanks mucho
