László Bodor commented on TEZ-4149:
-----------------------------------
thanks for the patch [~jeagles], it indeed improves further, with your conf the
3 threaded fair scheduled testRecovery_OrderedWordCount took: 230.083, 237.4,
232.466, 237.301 seconds in 4 consecutive runs (without the conf changes it was
between 260-270s)
I'm sharing my patch merged with your configs soon
> Speed up TezRecovery tests
> --------------------------

> Key: TEZ-4149
> URL: https://issues.apache.org/jira/browse/TEZ-4149
> Project: Apache Tez
> Issue Type: Sub-task
> Reporter: Jonathan Turner Eagles
> Assignee: László Bodor
> Priority: Major
> Attachments: TEZ-4149.WIP.patch,
> org.apache.tez.test.TestRecovery-output.txt
>
>
> Currently, approximately 50% of the tests cases are chosen to run as there
> are many failure points chosen to test recovery on.
> This can lead to the introduction of bugs into the code as not all test cases
> are run for every Tez QA run.
> In addition, this can be a real development bottleneck as tests take around
> 20 minutes per cycle if all tests are run (10 minutes if 50% of the tests are
> run as usual)
