-Mechanism of hadoop -jar
Jay Vyas 2012-08-11, 22:09
Hi guys: I'm trying to find documentation on how "hadoop jar" actually
works i.e. how it copies/runs the jar file across the cluster, in order to
debug a jar issue.
1) Where can I get a good explanation of how the hadoop commands (i.e.
-jar) are implemented ?
2) Specifically, Im trying to access a bundled text file from a jar :
from inside a mapreduce job.... Is it okay to do this ? Or does a classes
ability to aquire local resources change in the mapper/reducer JVMs ?
