Hi everyone! Recently, I updated my HDFS from 0.18.0 to 0.20.1 and installed
PigPen (0.04) for Eclipse Galileo under Windows. With the older version of
Hadoop (0.18) the plugin worked correctly and I was able to submit jobs to
the cluster, but with this new version I can´t. I also followed the
instructions in http://behemoth.strlen.net/~alex/hadoop20-pig-howto.txt, but
this is for 0.20.0 version. The question is: with the 0.20.1 version of
Hadoop and Pig 0.4.0 do I have to follow the same steps, or is not
necessary?
Thanks in advance.

That should work. Instead of building hadoop20.jar as suggested there, you
could use hadoop20.jar from PIG trunk.

Also you might have to apply a different patch from PIG-660 (try
660_5.patch).

Raghu.

FYI, the current Cloudera CDH2 Pig packages run on both 18 and 20 automagically.

You might have to muck about with them a bit to get them to see your
hadoop config files, but it should work pretty cleanly once you get
that going.

Thanks for the reply. I managed to get the plugin to work, applying
PIG_660_trunk2.patch instead PIG_660_4.patch. The rest was the same.
