Bad storm config persisted in zookeeper preventing nimbus from restarting
Hi,
We are using storm 0.9.0.1, and one topology got { "topology.workers",
nil} in the config and it crashed nimbus with this stack trace. Then each
time we try to restart nimbus it also crashes with the same stack trace. Is
the zookeeper in a bad state If so how do we clear it?
