----------------------------------------
Summary: Downgrade hsqldb dependency to 1.8
Key: MAPREDUCE-4498
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4498
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: build, examples
Affects Versions: 2.2.0-alpha
Reporter: Robert Kanter
Assignee: Robert Kanter
Priority: Critical
Fix For: 2.2.0-alpha
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.
