Robert Kanter updated MAPREDUCE-4498:
-------------------------------------
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. (was: 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 downgrade to 1.8.x to avoid conflicts for
the other projects.)
Summary: Remove hsqldb jar from Hadoop runtime classpath (was:
Downgrade hsqldb dependency to 1.8)
