Description

SelectHiveQL and PutHiveQL don't currently work with HTTP transport. There appears to be a class loader problem resulting in java.lang.NoClassDefFoundError: Could not initialize class org.apache.http.conn.ssl.SSLConnectionSocketFactory.

This looks like a conflict with the Apache commons httpclient version in hadoop-common. Removing the hadoop-libraries .nar dependency and provided scope for hadoop-common appears to fix the issue, but I haven't done any rigorous testing so I'm not sure if there are other consequences or not.
