Preparing the HBase cluster

Perform the following tasks to prepare the HBase cluster for NetBackup:

  • Update firewall settings (port 50070 by default) so that the backup hosts can communicate with the HBase cluster.

  • Add the entries of all the HMaster and region servers to the /etc/hosts file on all the backup hosts. You must add the hostname in FQDN format.

    Or

    Add the appropriate DNS entries in the /etc/resolve.conf file.

  • Add the entries of all the backup hosts to /etc/hosts file on the HMaster and region servers.

  • Ensure that HBase service is enabled on the HBase cluster.

  • HMaster user should be able to do SSH

  • Set the following environment variables for Hmaster in the .bashrc file for all users configured under tpconfig of master server.

    • export JAVA_HOME= PATH_OF_JAVA_DIR

    • export HADOOP_HOME=PATH_OF_HDFS_DIR

    • export HADOOP_MAPRED_HOME=$HADOOP_HOME

    • export HADOOP_COMMON_HOME=$HADOOP_HOME

    • export HADOOP_HDFS_HOME=$HADOOP_HOME

    • export YARN_HOME=$HADOOP_HOME

    • export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native

    • export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin

    • export HADOOP_INSTALL=$HADOOP_HOME

    • export HADOOP_OPTS="$HADOOP_OPTS -Djava.library.path=$HADOOP_HOME/lib/native"

    • export HBASE_HOME=PATH OF HBASE DIR

    • PATH=$PATH:$HBASE_HOME/bin:$JAVA_HOME/bin

    • export CLASSPATH=$CLASSPATH:/usr/local/hadoop/hbase/lib/*
