[jira] [Commented] (TEZ-1478)
TestContainerReuse.testReuseNonLocalRequest test is unstable
[ https://issues.apache.org/jira/browse/TEZ-1478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14118625#comment-14118625 ]
Alexander Pivovarov commented on TEZ-1478:
------------------------------------------
I found that result of testReuseNonLocalRequest is affected by the execution of previous test method - testReuseWithTaskSpecificLaunchCmdOption
In particular by line 572 : Container container1 = createContainer(1, "host1", resource1, priority1);
If I put testReuseNonLocalRequest method to a separate Test Class then the test always passes
Probably the easies way to fix the issue is to create new class TestContainerReuseNonLocalRequest and move testReuseNonLocalRequest method to this new class.
It will be more fair test execution because testReuseNonLocalRequest will be isolated from other test methods which create containers.
Similar situation with testDelayedReuseContainerBecomesAvailable - this method is executed the last and fails (however it is first in the class)
if I put this method to a separate class is always works
Probably we should put all methods from TestContainerReuse to separate classes to isolate them from other test methods.
What you think?
