Hello, Another newbie question. Suppose I want to use an external library (jar) in the mapper / reducer classes. (commons-lang, google's guava, etc.) In our environment, I added the jars into a specific folder and added them to HADOOP-CLASSPATH. However, when running mapper that uses one of the jars, it could not find the classes in that jar.
I thought that it might be in our environment (I am not managing our cluster). Then I read about DistributedCache. Should I use it with methods such as addArchiveToClassPath, addFileToClassPath, addCachArchive to use jar libraries? If so, which method is more appropriate ? If not, how do we load jar libraries to each VM?
