*I configure the regionservers in the file regsionservers as following:*
sha-cs-01
sha-cs-02
sha-cs-03
sha-cs-05
sha-cs-06
*And also I configure the zookeeper in file hbase-site.xml as following:*
<configuration>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
<description>The mode the cluster will be in. Possible values are
false: standalone and pseudo-distributed setups with managed Zookeeper
true: fully-distributed with unmanaged Zookeeper Quorum (see
hbase-env.sh)
</description>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2222</value>
<description>Property from ZooKeeper's config zoo.cfg.
The port at which the clients will connect.
</description>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>*sha-cs-01,sha-cs-02,sha-cs-03,sha-cs-04,sha-cs-06*</value>
<description>Comma separated list of servers in the ZooKeeper Quorum.
For example, "host1.mydomain.com,host2.mydomain.com,host3.mydomain.com
".
By default this is set to localhost for local and pseudo-distributed
modes
of operation. For a fully-distributed setup, this should be set to a
full
list of ZooKeeper quorum servers. If HBASE_MANAGES_ZK is set in
hbase-env.sh
this is the list of servers which we will start/stop ZooKeeper on.
</description>
</property>
<property>
<name>hbase.rootdir</name>
<value>hdfs://sha-cs-04:9000/hbase</value>
<description>The directory shared by region servers.
</description>
</property>
</configuration>
I still do not understand what's wrong with my configuration ?
