Subject [jira] [Commented] (HDFS-12345) Scale testing HDFS NameNode with real metadata and workloads (Dynamometer)
Date Thu, 28 Feb 2019 22:35:01 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16780994#comment-16780994

Erik Krogen commented on HDFS-12345:

Hm. I wonder if it even makes sense for MiniDFSCluster to depend on JUnit... Anyway, I solved
this problem in the GitHub repo by specifying JUnit as a [compile-time dependency|https://github.com/xkrogen/dynamometer/blob/ekrogen-hadoop-3-support/dynamometer-infra/build.gradle#L8].
This works even for the tarball since the tarball is set to [include all of the non-Hadoop
runtime dependencies|https://github.com/linkedin/dynamometer/blob/master/build.gradle#L100].
I'm not sure how to achieve the equivalent in Maven...

> To encourage getting the tool into the open for others to use as quickly as possible,
we went through our standard open sourcing process of releasing on GitHub. However we are
interested in the possibility of donating this to Apache as part of Hadoop itself and would
appreciate feedback on whether or not this is something that would be supported by the community.
