Description

We want to support running workers of older version on 2.x cluster. The most of work is done by STORM-2448. We need one more.

When we schedule a topology of older version, the confs in TopologyDetails could be "backtype.storm". To make scheduler work, we need to translate "backtype.storm" to "org.storm" for Config.TOPOLOGY_SCHEDULER_STRATEGY
