Hi everybody,
it was not an easy way to run a map reduce job at all, ie if a third party jars
are involved...
a good help is the article by cloudera:
http://www.cloudera.com/blog/2011/01/how-to-include-third-party-libraries-in-your-map-reduce-job/
i still can not use the -libjars argument for running a MR job with 3rd party
jars, like described in the first option
for some reason it does not work for me... the tasks fail with the
java.lang.ClassNotFoundException, classes of the 3rd party lib are not found
...
ups... :-)
the reasen for this was creating a new config
Configuration conf = HBaseConfiguration.create();
instead of using the one provided by the Configured super class
Configuration conf = getConf();
now the -libjars works like a charm :-)
but the other questions are still there...
