title: Trouble with HBase / Zookeeper installation
body: <p>I have a problem with installing hbase on Ubuntu 11.04. I'm new to ubuntu and actually a noob! Recently, I installed hadoop-0.20.2 on my laptop with single cluster configurations, and I ran WordCount example on it and it worked fine. Then, I tried installing hbase-0.90.3 as it is described in <a href="http://hbase.apache.org/book/quickstart.html" rel="nofollow">HBase quickstart</a>. When I started hbase and tried <code>create 'test', 'cf'</code> (the shell exercises) I got this error:</p>
  
  <pre><code>ERROR: org.apache.hadoop.hbase.ZooKeeperConnectionException: HBase is able to
  connect to ZooKeeper but the connection closes immediately. This could be a sign
  that the server has too many connections (30 is the default). Consider inspecting
  your ZK server logs for that error and then make sure you are reusing
  HBaseConfiguration as often as you can. See HTable's javadoc for more information.
  
  Here is some help for this command:
  Create table; pass table name, a dictionary of specifications per
  column family, and optionally a dictionary of table configuration.
  Dictionaries are described below in the GENERAL NOTES section.
  Examples:
    hbase&gt; create 't1', {NAME =&gt; 'f1', VERSIONS =&gt; 5}
    hbase&gt; create 't1', {NAME =&gt; 'f1'}, {NAME =&gt; 'f2'}, {NAME =&gt; 'f3'}
    hbase&gt; # The above in shorthand would be the following:
    hbase&gt; create 't1', 'f1', 'f2', 'f3'
    hbase&gt; create 't1', {NAME =&gt; 'f1', VERSIONS =&gt; 1, TTL =&gt; 2592000, BLOCKCACHE =&gt; true}
  </code></pre>
  
  <p>This is the log that hbase makes in logs folder: (the file <code>hbase-sepideh-master-sepideh.log</code> in my case)</p>
