[jira] [Commented] (HADOOP-14693) Upgrade JUnit from 4 to 5

["Ewan Higgs (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-14693?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16695205#comment-16695205 ] 

Ewan Higgs commented on HADOOP-14693:
-------------------------------------

In various tests (e.g. TestECSchema) we have {{@Rule Timeout globalTimeout = new Timeout(3000);}} which means the entire test and all child tests have a timeout set. Junit5 doesn't have this (yet). Discussion is here: 

https://github.com/junit-team/junit5/issues/80

I'm not sure if this is a blocker for anyone. If the tests behave well enough then maybe we can remove the timeouts?
