> In TEZ-1145, application is allowed to set -1 parallelism on a non 1-1 input
> vertex, and expect VertexManager to set the actual parallelism dynamically.
> However, when I does that, I hit the following exception:
> {code}
> org.apache.tez.dag.api.TezUncheckedException: vertex_1400869346120_0005_1_04
> has -1 tasks but neither input initializers nor 1-1 uninited sources
