You mean like that:
hadoop jar Rdg.jar my.hadoop.Rdg -libjars Rdg_lib/* tester rdg_output
Where Rdg_lib is the a folder containing all reqd classes/jars stored on
HDFS.
We get this error though. We do something wrong?

Hi Bertrand
-libjars option works well with the 'hadoop jar' command. Instead of
executing your runnable with the plain java 'jar' command use 'hadoop jar'
. When you use hadoop jar you can ship the dependent jars/files etc as
1) include them in the /lib folder in your jar
2) use -libjars / -files

Hi all,
I'm using textbook example (page 56) to move data from local file system to
HDFS. But there is an error in the line FileSystem fs =
FileSystem.get(URI.create(dst), conf);

Are you sure this patch will work for 0.20.205?

So does this patch also apply to 0

After you have installed snappy you have to configure the codec like the URL I

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