> I installed the hbase and hadoop under the Pseudo-Distributed mode:
> I configure the server side with following configuration:
> hadoop: core-site.xml
> <property>
> <name>fs.default.name</name>
> <value>hdfs://cluster1.office:9000</value>
> </property>
> hadoop:mapred-site.xml
> <property>
> <name>mapred.job.tracker</name>
> <value>localhost:9001</value>
> </property>
> hadoop:hdfs-site.xml
> <property>
> <name>dfs.replication</name>
> <value>1</value>
> </property>
> hbase:hbase-site.xml
> <property>
> <name>hbase.rootdir</name>
> <value>hdfs://cluster1.office:9000/hbase</value>
> <description>The directory shared by region servers.

> </property>
> I configure my client side(this is not in the same server as the server side)
> with following configuration:
> <property>
> <name>hbase.rootdir</name>
> <value>hdfs://cluster1.office/hbase</value>
> </property>
> <property>
> <name>hbase.zookeeper.quorum</name>
> <value>cluster1.office</value>
> </property>
> And then I connect to server side by java API described in the following page:

> Unfortunately I get the Out of memory error:
