> Hi, all,
> I just made a summary about the experiences to set up a pseudo-distributed mode HBase.
> 1) RedHat 9 is not suitable for running HBase and Hadoop. I don't know the reasons. Now Ubuntu is my choice.
> 2) After the pseudo-distributed mode of HDFS is configured, it is required to configure the hbase-env.sh and hbase-site.xml. The book, HBase the Definitive Guide, does not mentions hbase.env.xml.
> 3) It should set up JAVA_HOME, HBASE_CLASSPATH and HBASE_MANAGES_ZK. My hbase-env.sh is as follows.
> export JAVA_HOME=/opt/jdk1.6.1/
> export HBASE_CLASSPATH=/opt/hbase-0.92.0/conf
> export HBASE_OPTS="-XX:+UseConcMarkSweepGC"
> export HBASE_MANAGES_ZK=true
> 4) When configuring hbase-site.xml, the property, hbase.cluster.distributed, must be set also. The book, HBase the Definitive Guide, does not do that either. My hbase-site.xml is as follows.
> <?xml version="1.0"?>
> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
> <configuration>
> <property>
> <name>hbase.rootdir</name>
> <value>hdfs://localhost:9000/hbase</value>
> </property>
> <property>
> <name>dfs.replication</name>
> <value>1</value>
> </property>
> <property>
> <name>hbase.cluster.distributed</name>
> <value>true</value>
> </property>
> </configuration>
> I am a new user of HBase. Your suggestions are highly appreciated.
> Best regards,
> Bing
