Subject [jira] Created: (ZOOKEEPER-357) ZooKeeper cannot actually take care of a Zoo

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!
