Description

A number of Storm's dependencies regularly conflict with user dependencies:

• Netty (tends to conflict with Cassandra and others)
• Guava
• httpclient

Shading these into storm-core.jar and doing package relocation will eliminate dependency conflicts when user code (topologies) depends on conflicting versions.
