        Changes so the BookieServer's main method to create Bookie's will take in an additional parameter for the String of ZooKeeper servers (comma separated string of hostname:port). This is passed to the Bookie constructor which will invoke the ZK related client instantiation and creation of the ephemeral nodes for the Bookie Server being created.

        Thanks for the patch, Erwin! The patch you've uploaded does not apply, though. Could you please re-generate the patch having the zookeeper project folder as the root? The current patch apparently has the bookkeeper folder as the root instead.

        excellent work erwin! you need to modify BaseTestCase in the BookKeeper tests and remove the creating of the znodes under /ledgers/available in setUp(). that will allow the tests to exercise your code.

        Thanks for the new patch, Erwin. A couple of quick comments:

        1. There are several formatting changes in the patch unrelated to the issue, which is distracting;
        2. Although the patch applies, it does not compile. I get the following compilation error, which is not difficult to fix:
          [javac] zookeeper-apache-436/src/contrib/bookkeeper/src/java/org/apache/bookkeeper/util/LocalBookKeeper.java:136: cannot find symbol
            [javac] symbol  : constructor BookieServer(int,java.io.File,java.io.File[])

            [javac] 			bs[i] = new BookieServer(initialPort + i, tmpDirs[i], new File[]{tmpDirs[i]});

        I updated Erwin's patch in the following way:

        1. The patch committed yesterday for ZOOKEEPER-709 generated a conflict, so I fixed it;
        2. One of the tests was failing for me because we were not closing the zookeeper client object when shutting down a bookie. In general it shouldn't be a problem because the ephemeral znode goes away once the session expires, but in the case of testBookieRecovery, we shut down a bookie and re-start it right away, so there isn't enough time for expiration. Consequently, I have added a line to close the zk client object if zk is not null (it can be null if no server is passes as a parameter).

        Oops, I knew i'd miss something from porting over the changes made earlier. Yeah, doing the formatting changes does make doing a quick glance at svn diff hard. Had this change on the original version but missed it when porting changes over manually. Thanks for catching it!
