Until now we were manually copying our Jars to all machines in a Hadoop cluster. This used to work until our cluster size was small. Now our cluster is getting bigger. What's the best way to start a Hadoop Job that automatically distributes the Jar to all machines in a cluster?
I read the doc at: http://hadoop.apache.org/common/docs/current/commands_manual.html#jar Would -libjars do the trick? But we need to use 'hadoop job' for that, right? Until now, we were using 'hadoop jar' to start all our jobs. Needless to say, we are getting our feet wet with Hadoop, so appreciate your help with our dumb questions. Thanks. PS: We use Pig a lot, which automatically does this, so there must be a clean way to do this.
