Re: ClassNotFoundException: -libjars not working?
Hi, -libjars doesn't always work.Better way is to create a runnable jar with all dependencies ( if no of dependency is less) or u have to keep the jars into the lib folder of the hadoop in all machines.

Re: ClassNotFoundException: -libjars not working?
Pe 28.02.2012 10:58, madhu phatak a scris: Hi, -libjars doesn't always work.Better way is to create a runnable jar with all dependencies ( if no of dependency is less) or u have to keep the jars into the lib folder of the hadoop in all machines. Thanks for the reply Madhu, I adopted the second solution as explained in [1]. From what I found browsing the net it seems that -libjars is broken in hadoop version 0.18. I didn't got time to check the code yet. Cloudera released hadoop sources are packaged a bit odd and Netbeans doens't seem to play well with that and this really affects my will to try to fix the problem. -libjars is a nice feature that permits the use of skinny jars and would help system admins do better packaging. It also allows better control over the classpath. Too bad it didn't work.
