"""Fault tolerance test (small cluster, non-elastic training)
|
|
|
|
In this run, two training actors will die after some time. It is expected that
|
|
in both cases lightgbm_ray stops training, restarts the dead actors, and
|
|
continues training with all four actors.
|
|
|
|
Test owner: Yard1 (primary), krfricke
|
|
|
|
Acceptance criteria: Should run through and report final results. Intermediate
|
|
output should show that training halts wenn an actor dies and continues only
|
|
when all four actors are available again. The test will fail if fault
|
|
tolerance did not work correctly.
|
|
|
|
Notes: This test seems to be somewhat flaky. This might be due to
|
|
race conditions in handling dead actors. This is likely a problem of
|
|
the lightgbm_ray implementation and not of this test.
