One of the advantages of Bigtop is the ease of installation of the different Hadoop Components without having to hunt for a specific Hadoop Component distribution and matching it with a specific Hadoop version.
Please visit the link above to run some easy examples from the Bigtop distribution !
Provided at the link above are examples to run Hadoop 1.0.1 and nine other components from the Hadoop ecosystem (hive/hbase/zookeeper/pig/sqoop/oozie/mahout/whirr and flume).
See https://svn.apache.org/repos/asf/incubator/bigtop/trunk/bigtop.mk for a list of components , officially available from the Bigtop distribution.

Where to go from here

It is highly recommended that you read documentation provided by the Hadoop project itself
