According to https://issues.apache.org/jira/browse/HADOOP-7470 hadoop 1.x has
been upgraded to jackson 1.8.8 but the POM file still specifies jackson 1.0.1
which doesn't work for hive (doesn't have the ALLOW_UNQUOTED_CONTROL_CHARS).
The POM for hadoop 2.0.0-alpha (-Dhadoop.mr.rev=23) has the right dependency,
hadoop 0.20.2 (-Dhadoop.mr.rev=20) doesn't depend on jackson.
