Subject: ERROR: org.apache.hadoop.hbase.ZooKeeperConnectionException:

Hi Friends,

I am newbee in Hbase. I was trying to setup Hbase with Quick start tutorial. But facing issues
in creating the table :

Below is the error on Hbase shell :

hbase(main):001:0> create 'test','cf'

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> create 't1', {NAME => 'f1', VERSIONS => 5}
  hbase> create 't1', {NAME => 'f1'}, {NAME => 'f2'}, {NAME => 'f3'}
  hbase> # The above in shorthand would be the following:
  hbase> create 't1', 'f1', 'f2', 'f3'
  hbase> create 't1', {NAME => 'f1', VERSIONS => 1, TTL => 2592000, BLOCKCACHE
=> true}

Contents of my /etc/hosts :

127.0.0.1   localhost
<IP> localhost

Contents of hbase-site.xml :

<configuration>
<property>
    <name>hbase.rootdir</name>
    <value>/opt/Hbase/hbase-root1</value>
  </property>
</configuration>

Please Help

Stuti
