Rohini Palaniswamy commented on PIG-3285:
-----------------------------------------
bq. I am not sure if we double ship those jars if we doing this. Actually I
would prefer a TableMapReduce.addDependencyJars version which only adds
hbase.jar/guava.jar/protobuf.jar and additional dependencies when hbase evolves
(but no hadoop.jar/pig.jar)
Nick, Looking at the code I am sure we will end up double shipping jars which
is very inefficient. It would be good to write a separate function instead of
TableMapReduce.addDependencyJars(job) that filters out pig and hadoop jars
(classes starting with org.apache.pig and org.apache.hadoop) and those in
pigContext.extraJars from the list of classes in
TableMapReduce.addDependencyJars(job) and then set them on tmpjars. You can
reuse JarManager.findContainingJar to find the jar for a class file.
