Kuhu Shukla commented on TEZ-3458:
----------------------------------
[~mingma], TestFaultTolerance#testCartesianProduct seems to hang after this
commit( The DAG is stuck in RUNNING state and waits indefinitely). The mvn
build fails as follows:
{code}
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-surefire-plugin:2.14.1:test (default-test) on
project tez-tests: There was a timeout or other error in the fork -> [Help 1]
{code}
Skipping this specific test allows the build to pass.

> Original CartesianProductVertexManagerUnpartitioned set parallelism as
> product of all source vertices parallelism which may explode to insane
> number. We should do auto reduce as in ShuffleVertexManager to avoid this.
