Description

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.
