Siddharth Seth commented on TEZ-1151:
-------------------------------------
What's the main difference between the two "TEZ-1151.2.patch" files ? I had the
older one downloaded yesterday. Please avoid uploading and overwriting the same
file - can get fairly confusing for reviewers.

> 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:

> org.apache.tez.dag.api.TezUncheckedException: vertex_1400869346120_0005_1_04
