Subject Re: help for snappy
Date Mon, 27 Feb 2012 06:59:15 GMT
After you have installed snappy you have to configure the codec like the URL I posted before
or you can reference them in your MR jobs. Be sure you have the jars in your classpath for.


For storing snappy compressed files in HDFS you should use Pig or Flume.
