Srikanth Sundarrajan created FALCON-691:
-------------------------------------------

             Summary: Build issues - Hadoop-2 profile
                 Key: FALCON-691
                 URL: https://issues.apache.org/jira/browse/FALCON-691
             Project: Falcon
          Issue Type: Bug
          Components: build-tools, oozie
    Affects Versions: 0.5, 0.6
            Reporter: Srikanth Sundarrajan
            Assignee: Srikanth Sundarrajan
            Priority: Blocker
             Fix For: 0.5, 0.6


Unable to compile falcon code in Hadoop-2 profile.

The issue is hadoop 2.4 depends on httpcomponents:httpclient 4.2.5, while hive-10 depends
on httpcomponents:httpclient 4.1.3 and the two versions of httpclient aren't compatible and
oozie builds with hive-10 by default and falcon builds with hive-13 by default, resulting
in both 4.1.3 & 4.2.5 jars of httpclient being in classpath. Result is that the build
isn't predictable.

Errors observed during build:

The issue is apparent in the snippet below when hadoop-webapp is being built the oozie.war
is shown to have both versions of hive besides both version of httpcomponents.

The fix is to exclude httpcomponents from hive-metastore, hive-webhcat and oozie-webapp dependencies
besides bumping up the version of hive by default when oozie is built.
