access hbase table fron hadoop mapreduce

Question

I want to access hbase table from hadoop mapreduce and I'm using windowsXP, cygwin, hadoop-0.20.2 and hbase-0.92.0. I am able to run mapreduce wordcount successfully on 3 pcs and have verfied that hadoop and hbase are working fine. I can also create table from shell.

I have tried many examples but they are not working, for example when I try to compile it using javac Example.java

it gives error..... org.apache.hadoop.hbase.client does not exist org.apache.hadoop.hbase does not exist org.apache.hadoop.hbase.io does not exist

please can anyone help me in this...... -plz give me some example code to access hbase from hadoop map reduce -also guide me how should I compile and execute it?

Answer 1

This website has example hbase/Mapreduce code. I haven't tried it, but it looks OK at first glance. Also what distribution of Hadoop/HBase are you using? Apache? Cloudera?
