Subject [jira] [Commented] (REEF-1464) Fix TestTaskCloseOnLocalRuntime failures in AppVeyor
Date Mon, 05 Dec 2016 22:44:59 GMT

    [ https://issues.apache.org/jira/browse/REEF-1464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15723609#comment-15723609
] 

Mariia Mykhailova commented on REEF-1464:
-----------------------------------------

I've filed REEF-1684 for the proper fix. As a mitigation, I'll configure {{MaxConnectionRetry}}
and {{SleepTime}} to smaller values for this test, so that even this test hits scenario when
task cancellation goes through all the retries, it will be done sooner.

> {{O.A.R.Tests.Functional.IMRU.IMRUCloseTaskTest.TestTaskCloseOnLocalRuntime}} fails frequently
in AppVeyor test runs. The error is typically "Cannot read from log file" with rest runtime
65-70 seconds, and according to our current thinking in REEF-1417 this is caused by Evaluator(s)
still running after 60 seconds of test execution. 
> [In one case|https://ci.appveyor.com/project/ApacheSoftwareFoundation/reef/build/641-master/tests]
the test completed in 38 seconds, with error message
> {noformat}
> Assert.Equal() Failure
> Expected: 4
> Actual:   5
> at 
> Assert.Equal(numTasks, failedCount + completedCount);
> {noformat}
> In [successful run|https://ci.appveyor.com/project/ApacheSoftwareFoundation/reef/build/644-master/tests],
the test takes 30 seconds.
> We need to investigate whether IMRU job itself takes longer than 60 seconds on AppVeyor
machines, or whether Evaluator doesn't close properly.
