[Hbase] Addition of Hbase Examples
----------------------------------

                 Key: HADOOP-2415
                 URL: https://issues.apache.org/jira/browse/HADOOP-2415
             Project: Hadoop
          Issue Type: New Feature
          Components: contrib/hbase
    Affects Versions: 0.16.0
         Environment: All
            Reporter: Edward Yoon
            Assignee: Edward Yoon
             Fix For: 0.16.0


I decided to move the relational algebra operators to example package after some discuss with
Hbase committers.

{code}
hql > jar ./build/contrib/hbase/hadoop-0.16.0-dev-hbase-examples.jar
An example program must be given as the first argument.
Valid program names are:
   apachelogfetcher: A apache access_log fetcher
   tableprojection: Selects a subset of the columnfamilies of a relation
   tableselection: Selects a subset of the rows in a relation that satisfy a selec
   t condition
   .... 

hql > jar ./build/contrib/hbase/hadoop-0.16.0-dev-hbase-examples.jar tableprojection
Usage: tableprojection input output "column-list"
hql > jar ./build/contrib/hbase/hadoop-0.16.0-dev-hbase-examples.jar tableprojection movieLog_table
projectedTable "year: length:"
...
{code}
