Subject HBase with HDFS - Setup problem
Date Wed, 06 Aug 2008 10:41:13 GMT
Morning all,
 
I'm attempting to setup HBase 0.1.3 to run on top of the Hadoop 0.17.1
DFS, however I'm having trouble. HBase is running at the moment (I can
enter the shell, and create/show tables), however stopping the HDFS has
no effect, therefore suggesting that HBase is running using the local
filesystem rather than the HDFS. I'd really appreciate any suggestions!
 
Below is my hbase-site.xml file:

	<configuration>
	  <property>
	    <name>hbase.rootdir</name>
	    <value>hdfs://127.0.0.1:9000/hbase</value>
	    <description>The directory shared by region servers.
	    Should be fully-qualified to include the filesystem to use.
	    E.g: hdfs://NAMENODE_SERVER:PORT/HBASE_ROOTDIR
	    </description>
	  </property>
	    <property>
	    <name>hbase.master</name>
	    <value>local</value>
	    <description>The host and port that the HBase master runs
at.
	    A value of 'local' runs the master and a regionserver in
	    a single process.
	    </description>
	  </property>
	</configuration>
	 
	 

And my hadoop-site.xml:

	 <property>
	  <name>fs.default.name</name>
	  <value>hdfs://127.0.0.1:9000</value>
	 </property>
	 
	    <property>
	        <name>mapred.job.tracker</name>
	        <value>hdfs://127.0.0.1:9001</value>
	    </property>
	 
	 <property>
	  <name>dfs.name.dir</name>
	  <value>/usr/hadoop/hdfs/name</value> 
	 </property>
	 
	 <property>
	  <name>dfs.data.dir</name>
	  <value>/usr/hadoop/hdfs/data</value>
	 </property> 
	 
	    <property>
	        <name>dfs.replication</name>
	  <value>3</value>
	    </property>
	 
	 <property>
	  <name>mapred.child.java.opts</name>
	  <value>-Xmx2000m</value>
	 </property>
	 
	 <property>
	  <name>mapred.map.tasks</name>
	  <description>10x number of slaves</description>
	        <value>120</value>
	    </property>
	

Regards,
Chris Paterson
