Hi guys,
I'v tried to install HBASE 0.98 on a CentOS linux server. I tried different
settings but always get one specific Zookeeper error message. my final
configuration is as follow
/etc/hosts:
127.0.0.1 localhost
192.168.1.101 node1
-----------------------------------------
hbase-site.xml:
<property>
<name>hbase.rootdir</name>
<value>file:///hadoop/hbase/hbase-0.98.11-hadoop2/data/</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>node1</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>file:///hadoop/hbase/hbase-0.98.11-hadoop2/data/zookeeper</value>
</property>
-----------------------------------------

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.
