Ahmed Hussein created HADOOP-17769: -------------------------------------- Summary: Upgrade JUnit to 4.13.2 Key: HADOOP-17769 URL: https://issues.apache.org/jira/browse/HADOOP-17769 Project: Hadoop Common Issue Type: Bug Reporter: Ahmed Hussein Assignee: Ahmed Hussein
JUnit 4.13.1 has a bug that is reported in Junit [issue-1652|https://github.com/junit-team/junit4/issues/1652] _Timeout ThreadGroups should not be destroyed_ After upgrading Junit to 4.13.1 in HADOOP-17602, {{TestBlockRecovery}} started to fail regularly in branch-3.x and branch-2.10. While investigating the failure in branch-2.10 HDFS-16072, I found out that the bug is the main reason {{TestBlockRecovery}} started to fail because the timeout of the Junit would try to close a ThreadGroup that has been already closed which throws the {{java.lang.IllegalThreadStateException}}. The bug has been fixed in Junit-4.13.2 For branch-3.x, HDFS-15940 did not address the root cause of the problem. Eventually, Splitting the {{TestBlockRecovery}} hid the bug, but the upgrade needs to be done so that the problem does not show up in another unit test. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
