@Renato,
the end goal is to be able to run in command line using
hadoop jar your.jar your.mr.class.name
so it will run on all cluster machines.
So if you can do this, that is pretty good

Not sure why you aren’t able to run it within Eclipse…

Hi I tried this:
http://wiki.apache.org/hadoop/Hbase/MapReduce
with no success. Though I am able to execute my job regularly from the command line, and as a java program, any ideas or suggestions are highly appreciated. Thanks in advanced.

@Renato
Your hadoop installation doesn’t know about Hbase classes.

Check ’step 0′ under ‘Hbase setup’ section. Or you can follow this:
http://hadoop.apache.org/hbase/docs/r0.20.3/api/org/apache/hadoop/hbase/mapreduce/package-summary.html
Once you modify your file, make sure to DISTRIBUTE the hadoop-env.sh across the cluster.

Hey Sujee!! Really nice and helpful post, thanks a lot!!! Though I have a little doubt, I am still learning Hadoop MapReduce and I was wondering why I can’t see the jobs I am executing on my localhost:50030?? I tried to executed from eclipse using the cluster I set up, but I got an error that said

Exception in thread “main” java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration

any idea??? Thanks a lot in advance (=

Hi Sujee!

Excellent post indeed, thank you for taking the time! Also please consider linking it into the HBase Wiki, so that other can find it easily (if you have not done so already) – simply register and edit the appropriate page. Much appreciated!

Excellent tutorial Sujee!

With the filter, someone should also use scan.setCaching so speed up the job.

@SansaUser
good catch, it is a BASH script. So changing
#!/bin/sh
to
#/bin/bash
is the way to go.

Not sure about the iconv errors, though.
