Hello Zhengguo ,

Yes , -libjars is the new feature in Hadoop. This feature has been =
available from Hadoop-0.17.x , but it is more stable from hadoop 0.18.x=20

example to use -libjars...

hadoop jar -libjars <comma seperated list of jars> ...


Thanks ,

Hi, Amareshwari,

Is -libjars a new option in Hadoop 0.19? I am using 0.17.2. The only =
option I see is -jar, which didn't work for me. And besides passing them =
as jar file, is there any other ways to do that?

Thanks
Mike

Hi,

How are you passing your classes to the pipes job? If you are passing=20
them as a jar file, you can use -libjars option. From branch 0.19, the=20
libjar files are added to the client classpath also.

Thanks
Amareshwari
