Bikas Saha commented on TEZ-1569:
---------------------------------
Patch adds e2e tests for preemption by using local mode and custom container
launcher to quickly simulate job execution without launching any tasks. It
simulates preemption by sending the preemption event to the engine in exactly
the same manner in which YARN sends the preemption event. This enables us to
explicitly specify the exact tasks we want to preempt and check for expected
behavior.
The patch tests.
In session mode, different combinations of DAG edges and vertices with
different number of preempted attempts
In non-session mode, multiple preemptions for one case of a DAG.
[~tassapola] Please review. Thanks!
