  == Pre-requisites ==
  Chukwa should work on any POSIX platform, but GNU/Linux is the only production platform that has been tested extensively. Chukwa has also been used successfully on Mac OS X, which several members of the Chukwa team use for development.
  
- The only absolute software requirements are Java 1.6 or better and Hadoop 0.20+. HICC, the Chukwa visualization interface, requires HBase 0.20.6.
+ The only absolute software requirements are Java 1.6 or better and Hadoop 0.20.203+. HICC, the Chukwa visualization interface, requires HBase 0.90.3.
  
  The Chukwa cluster management scripts rely on ssh; these scripts, however, are not required if you have some alternate mechanism for starting and stopping daemons.

  For data analytics with pig, there are some additional environment setup.  Pig does not use the same environment variable name as Hadoop, therefore make sure the following environment are setup correctly:
  
   1. export PIG_CLASSPATH=$HADOOP_CONF_DIR:$HBASE_CONF_DIR
-  1. Setup a cron job for "pig -Dpig.additional.jars=${HBASE_HOME}/hbase-0.20.6.jar:${PIG_PATH}/pig.jar ${CHUKWA_HOME}/script/pig/ClusterSummary.pig" to run periodically
