HBase Installation (Standalone mode/local file system)

Requirements

• Java 1.5.x, preferably from Sun.
• Hadoop 0.16.x. This version of HBase will only run on Hadoop 0.16.x..
• ssh must be installed and sshd must be running to use Hadoop’s scripts    to manage remote Hadoop daemons.
• HBase currently is a file handle hog. The usual default of 1024 on *nix systems    is insufficient if you are loading any significant amount of data into regionservers.   See the FAQ: Why do I see “java.io.IOException…(Too many open files)” in my logs?  for how to up the limit.

[C] Installation of HBase

1. Java 1.5.x
   • installed java 1.6.x
   • Not sure whether 1.6.x will work
2. Unzipped the Hadoop archive file (ver 1.3) at ~/hbase
3. ssh & sshd configuration (execution)
   • sudo apt-get install openssh-server
   • sudo /etc/init.d/ssh start (stop)
4. edit the limit number of file handlers
   • checked /etc/security/limits.conf but there is no option to edit for this

[C] HBase Configuration

1. ${HBASE_HOME} : the real location of hbase (/home/luran/hbase)
2. modify JAVA_HOME information on ${HBASE_HOME}/conf/hbase-env.sh
3. start HBase by ${HBASE_HOME}/bin/start_hbase.sh
4. stop HBase by ${HBASE_HOME}/bin/stop-hbase.sh
