Hi
I have a map/reduce job that uses external jar files. How do I specify those
jars in the classpath when submitting the mapred job using ./hadoop jar ....
? Suppose my map job relies on API in some external jar how do I pass this
jar file as part of my job submission.
As far as I understand (that's what we do anyway), you have to submit one
jar that contains all your dependencies (except for dependencies on hadoop
libs), including external jars. The easiest is probably to build maven/ant
to build such "big" jar externally with all its dependency jars unpacked
and added into the jar, and then submit them to hadoop.
