NoNodeException In Log Files

I am seeing the following error in my master_bashi.debug.log file:

org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode
= NoNode for /accumulo/bf7909f7-26d6-43f2-bc43-c0534414305d/recovery

Could this be caused by the ZooZap issue that I ran into?

I was wrong. I created a /tmp/foo file and rebooted. My laptop machine
does clear /tmp on every reboot. This probably explains some of the
weirdness that I have experienced. Thank you for pointing out so basic
a possibility.

Mine is set to 60 days.

There is a setting in /etc/default/rcS

# delete files in /tmp during boot older than x days.
# '0' means always, -1 or 'infinite' disables the feature
TMPTIME=60

Yours may not be zero. Check yours. If it aligns with the date range
you suggested, below, then Jim probably had the answer, but with
different periodicity.

No argument, But on this particular machine, I have rebooted many
times without a problem. Only since the latest update from SVN have I
run into this issue.

Not sure what the zoozap issue was, but zookeeper in /tmp is a bad
idea. a lot of systems clear /tmp on startup so you could lose
everything that accumulo persisted to zookeeper on a reboot.

What did you set the "dataDir" ZooKeeper configuration parameter to in 
$ZOOKEEPER_HOME/conf/zoo.cfg?
