Setting up Snappy compression in Hadoop

[Amit Sela]

Hi all,

I'm running on Hadoop 1.0.4 and I'd like to use Snappy for map output
compression.
I'm adding the configurations:

configuration.setBoolean("mapred.compress.map.output", true);
configuration.set("mapred.map.output.compression.codec",
"org.apache.hadoop.io.compress.SnappyCodec");

And I've added libsnappy.so.1 to $HADOOP_HOME/lib/native/Linux-amd64-64/

Still, all map tasks fail with "native snappy library not available".

Could anyone elaborate on how to install Snappy for Hadoop ?

Thanks,

Amit.
