      Description

      The hsqldb jar is included in hadoop for the DBCountPageView example only. Currently the example is using hsqldb version 2.x; however, 2.x is incompatible with 1.8.x – having this jar in the hadoop class path conflicts with dependent projects like Oozie, Hive, and Pig which still use 1.8.x. As there are no features hsqldb 2.x that are used by the example, we should remove it from Hadoop's runtime classpath.

As there are no features hsqldb 2.x that are used by the example, we should downgrade to 1.8.x to avoid conflicts for the other projects.
