Hi George,
thanks for you reply and sorry for the silly mistake.
I change the hbase-site.xml to this:
<configuration>
<configuration>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.rootdir</name>
<value>hdfs://dev32:9000/hbase</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>dev32</value>
</property>
</configuration>
</configuration>
and sync it with slave nodes. but I am still getting the same problem.
I also run the flume instance on the same cluster. Do the flume and hbase
share the same zookeeper? Is this the reason why I get this problem?
