Subject [jira] [Commented] (HDFS-12254) Upgrade JUnit from 4 to 5 in hadoop-hdfs
Date Wed, 09 Aug 2017 17:33:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12254?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16120316#comment-16120316

Ajay Yadav commented on HDFS-12254:
-----------------------------------

hi [~ajisakaa] , As i understand , we can do it in two ways.
# 1. Update the junit dependency in hadoop-main to junit5 with junit-jupiter-engine. which
will require changes in most of the test cases to move them to new junit5 api and platform.
(More riskier)
# 2. Update the junit dependency in hadoop-main to junit5 while maintaining backward compatibility
to test cases built in junit4 using (junit-vintage-engine). As a next step we can create new
test cases using junit 5 api and move old test cases to junit5 in steps. This will be incremental
change with less risk to breaking old test cases.

Any ideas, suggestions on this?
