Gunther Hagleitner updated HIVE-3717:
-------------------------------------
Attachment: HIVE-3717.1-1410543.txt
The patch follows some other examples in the ivy config to not download the
hadoop 1.x jackson dependency. That let's you compile hive against 20S.
The real fix will be to update the POM file for hadoop core though.
> Hive won't compile with -Dhadoop.mr.rev=20S

> 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.
