-------------------------------------

    Attachment: MAPREDUCE-4498-v3.patch

The TestCombineFileInputFormat test fails even without the patch; so it seems to be unrelated.

> 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.
