LALAYANG opened a new pull request #3298: URL: https://github.com/apache/hadoop/pull/3298
Link to issue: [https://issues.apache.org/jira/browse/MAPREDUCE-7361](https://issues.apache.org/jira/browse/MAPREDUCE-7361) ## What is the purpose of this change This PR is to clean the polluted shared status among the 3 tests: ``` Test1: org.apache.hadoop.mapred.TestTaskProgressReporter.testBytesWrittenRespectingLimit Test2: org.apache.hadoop.mapred.TestTaskProgressReporter.testScratchDirSize Test3: org.apache.hadoop.mapred.TestTaskProgressReporter.testTaskProgress ``` - Test1 and Test2 pollute the shared status with Test3, which can make test3 fail. - It may be better to clean state pollutions so that some other tests won't fail in the future due to the shared state polluted by this test. ## Reproduce the test failures Run the tests in the same JVM in the following orders: - Test1 and Test3 - Test2 and Test3 ## Expected result The tests should run successfully when multiple tests that use this shared state are run in the same JVM. ## Actual result - Run Test1 and Test3, Test3 fails: ``` [ERROR] TestTaskProgressReporter.testTaskProgress:267 expected:<[2]> but was:<[3]> ``` - Run Test2 and Test3, Test3 fails: ``` [ERROR] TestTaskProgressReporter.testTaskProgress:267 expected:<[2]> but was:<[11]> ``` ## Fix Clean the value of `statusUpdateTimes` to 0 at the start of Test3 to clean the pollution from Test1 and Test2. -- This is an automated message from the Apache Git Service.
