Kareem,
Have you built Hadoop from its sources by using Ant or have
you
downloaded the (precompiled) distribution?
Only in the first case you actually have both
$/build/classes and
$/build/contrib/hbase/classes.
And in this case, are you sure that the HADOOP_HOME variable
is properly
set in the environment where you compile your class?
If you downloaded the (e.g. 0.15.0) distribution then you
have to add
the $/hadoop-0.15.0-core.jar and
$/contrib/hadoop-0.15.0-hbase.jar.
...and again, be sure to have HADOOP_HOME properly set.
Cheers,
Holger
