Added a problem wrt starting a ZK server

   1. [#9 Problem: Zookeeper SessionExpired events]
   1. [#10 Problem: Scanners keep getting timeouts]
   1. [#11 Problem: Client says no such table but it exists]
+  1. [#12 Problem: Could not find my address: xyz in list of ZooKeeper quorum servers]
  == 1. Problem: Master initializes, but Region Servers do not ==
@@ -178, +179 @@

  === Resolution ===
   * Run major compaction on the .META. table.  In the shell, type '''tool''' to learn how
to run a major compaction from the shell.
+ [[Anchor(12)]]
+ == 12. Problem: Could not find my address: xyz in list of ZooKeeper quorum servers ==
+  * A Zookeeper server wasn't able to start, throws that error. xyz is the name of your server.
+ === Causes ===
+  * This is a name lookup problem. HBase tries to start a ZK server on some machine but that
machine isn't able to find itself in the '''hbase.zookeeper.quorum configuration'''.
+ === Resolution ===
+  * Use the hostname presented in the error message instead of the value you used. If you
have a DNS server, you can set '''hbase.zookeeper.dns.interface''' and '''hbase.zookeeper.dns.nameserver'''
in hbase-site.xml to make sure it resolves to the correct FQDN.
