I want to install snappy on Hadoop 1.2.1. How do I do that?

0 votes

I added following properties in mapred-site.xml file for compressing my map files.

<property>
  <name>mapred.compress.map.output</name>  
  <value>true</value>
</property>
<property>
  <name>mapred.map.output.compression.codec</name>  
  <value>org.apache.hadoop.io.compress.SnappyCodec</value>
</property>

It's giving an Error of snappy_library not loaded.I think I'll have to install it before using the codecs.Kindly help.
