Subject [jira] [Updated] (HIVE-3717) Hive won't compile with -Dhadoop.mr.rev=20S
Date Sun, 06 Jan 2013 07:48:12 GMT

     [ https://issues.apache.org/jira/browse/HIVE-3717?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gunther Hagleitner updated HIVE-3717:
-------------------------------------

    Attachment: HIVE-3717.2.patch

More dependency fixes to compile and run tests with 20S (hadoop 1.0.0). Agreed this won't
be necessary when 1.1.2 becomes available (fixes all the dependency issues). However, 1.1.2
isn't out yet and 1.1.1 is being replaced by 1.1.2 (major bug).

> 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.
