 4. Validate the Installation

Use these steps to validate your installation.

  1. Start HBase and ZooKeeper.

    1. Execute this command from the each ZooKeeper node:

      <login as $ZOOKEEPER_USER>
/usr/lib/zookeeper/bin/zkServer.sh start $ZOOKEEPER_CONF_DIR/zoo.cfg

    2. Execute this command from the HBase Master node:

      <login as $HDFS_USER>
/usr/lib/hadoop/bin/hadoop fs -mkdir /apps/hbase
/usr/lib/hadoop/bin/hadoop fs -chown -R hbase /apps/hbase
<login as $HBASE_USER>
/usr/lib/hbase/bin/hbase-daemon.sh --config $HBASE_CONF_DIR start master

    3. Execute this command from each HBase Region Server node:

      <login as $HBASE_USER>
/usr/lib/hbase/bin/hbase-daemon.sh --config $HBASE_CONF_DIR start regionserver

      where:

      • $HBASE_CONF_DIR is the directory to store the HBase configuration files. For example, /etc/hbase/conf.

      • $HBASE_USER is the user owning the HBase services. For example, hbase.

      • $ZOOKEEPER_CONF_DIR is the directory to store the ZooKeeper configuration files. For example, /etc/zookeeper/conf.

      • $ZOOKEEPER_USER is the user owning the ZooKeeper services. For example, zookeeper.

  2. Smoke Test HBase and ZooKeeper.

    From a terminal window, enter:

    su - $HBASE_USER
hbase shell

    In the HBase shell, enter the following command:

    status
