Couldn't actually try on a ubuntu box. But found a page, which mentions the same command

this is in fact the package we use in the Dockerfile build script. https://github.com/apache/hadoop/blob/trunk/dev-support/docker/pkg-resolver/packages.json#L264

I merged this PR. But it would be nice to create an Apache JIRA next time.

I will create that jira before i cherrypick to branch3.3

[steveloughran]

created https://issues.apache.org/jira/browse/HADOOP-18214 for this; cherrypicked with that jira in the title to branch 3.3.3 and 3.3

Hi @gvieri, thank you for your contribution!

Could you let me know your ASF JIRA account? I want to set you as the assignee of https://issues.apache.org/jira/browse/HADOOP-18214

[gvieri]

It is necessary to have ASF JIRA account ?

[ayushtkn]

@gvieri well yes. This one got committed initially without a Jira since it wasn’t changing the core code, but in general we tend to have jira for almost everything. That’s how we track issues.

BTW. If you have a Jira account and have it assigned on your name. You will get the credit in the Release Notes as well when Hadoop does the release. Just one of the things if that interests or motivates you :-)
