Question about the hadoop-core-0.20.2.jar
Hi all,
I made some changes in hadoop and generated the updated version of
hadoop-core-0.20.2.jar to replace the one under pig/build/ivy/lib/pig. But
when I tried to use ant to get new pig.jar, it still told me that the new
method I added in hadoop counldn't be found.
Any idea?
Thanks

Why do you need hadoop in pig jar at all?
Just build the jar-withouthadoop target and use whatever hadoop jar
you like on your classpath.

Hello Chaitanya,
It still didn't work. I think the reason is in pig 0.8 it actually downloads
the hadoop from online repository instead of using the jar under build
directly. When I deleted the jar and ran ant, a new hadoop-core-0.20.2.jar
was generated again.
I think I will switch back to pig 0.7
Thanks

Hi Qi,
Can you try cleaning the build and then build jar afresh, by using 'ant
clean jar'? As per what i see in ant target, it takes the hadoop jar from
build directory. So, cleaning it up and building afresh might work.
Hope this helps,
Thanks,
Chaitanya.
