Subject [jira] [Commented] (HIVE-5755) Fix hadoop2 execution environment
Date Thu, 14 Nov 2013 22:49:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13823065#comment-13823065
] 

Brock Noland commented on HIVE-5755:
------------------------------------

The issue now is that hive-shims depends on hive-shims-0.20, hive-shims-0.20S, and hive-shims-0.23.
ql depends on hive-shims. When ql brings in hive-shims it brings it all transitive dependencies
which include three different versions of hadoop.  Since hive-shims should not bring any dependencies
with it because we expect the end-user module to bring it's hadoop hadoop version.

One way to do that is to mark all the hive-shims-* dependencies in hive-shims optional.  Does
that make sense?

> It looks like the hadoop2 execution environment isn't exactly correct post mavenization.
