Hi Bejoy,

Thanks for the reply.
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.

Thank you,
Sachin

Go to $HADOOP_HOME/config open and edit core-site.xml

Add a new property 'io.compression.codecs' and assign the required compression codecs as its value.

Hi,

I'm not using CM. I have installed CDH 4.2.1 using Linux packages.

Thank you,
Sachin

This property needs to be set in core-site.xml. 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.

Sanjay
