I would like to know "what" are the codecs that are available by default in the Hadoop system, among which i can choose to set in the core-site.xml. For ex: LZO compression codecs are not available by default and we have to install the required libraries for it.

If u r using clouderamanager then ping me I will tell u how to set it there. Out of the box hive works beautifully with gzip and snappy. And if u r using lzo then needs some plumbing. Depends on what ur usecase is I can provide guidance.
