ZooKeeper cannot actually take care of a Zoo

                 Key: ZOOKEEPER-357
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-357
             Project: Zookeeper
          Issue Type: Bug
            Reporter: Benjamin Reed
            Priority: Critical

Last week I setup an unattended ZooKeeper cluster that I expected to be able to 
take care of things while I was on vacation. I used 7 dedicated servers with 
two disks. I had done extensive burn in testing of the servers, so I fully 
expected the system to work problem free for the entire week. Indeed, when I 
returned yesterday none of the 7 servers had any hardware or software problem 
the entire time nor had there been any network problems. On the other hand the 
Zoo was in complete chaos. Even though there were no errors in the ZooKeeper 
log most of the animals were near starvation, except for the lions who had 
gotten loose and eaten some of the pigs. I'll not even go into the stench from 
the dirty cages!

Either the documentation needs to more clearly explain how to configure the 
server properly in the Zoo environment, or it should clearly state that 
ZooKeeper cannot take care of the Zoo out of the box!
