Subject Re: Accumulo not starting anymore
Date Wed, 16 Apr 2014 23:51:34 GMT
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/
