JAVA_HOME
to the root of your Java installationFirst, you need a working instance of Hadoop. Download a recent release from
Hadoop downloads.
Unpack the release and connect to its top-level directory. Let this be
${HADOOP_HOME}
. Edit the file ${HADOOP_HOME}/conf/hadoop-env.sh
to define at least JAVA_HOME
. Also, add site-particular
customizations to the file ${HADOOP_HOME}/conf/hadoop-site.xml
.
Try the following command:
bin/hadoop
Next, change to the hbase root. Let this be ${HBASE_HOME}
It is
usually located at ${HADOOP_HOME}/src/contrib/hbase
. Configure hbase.
Edit ${HBASE_HOME}/conf/hbase-env.sh
and
${HBASE_HOME}/conf/hbase-site.xml
to make site particular settings.
List the hosts running regionservers in ${HBASE_HOME}/conf/regionservers
.
Here is how to start and then stop hbase:
${HBASE_HOME}/bin/start-hbase.sh ${HBASE_HOME}/bin/stop-hbase.shLogs can be found in ${HADOOP_LOG_DIR}.
To obtain a shell against a running hbase instance, run:
${HBASE_HOME}/bin/hbase shellOnce the shell is up, type
help;
to see list of supported commands.
