[~bharatviswa], the maven-enforcer-plugin message already contains the information about the hadoop.version is required.

This means that if a parent project uses a variable, then its > definition in the child, not the parent, will be the one eventually used. > {quote} > The community voted to keep ozone in-tree but use a different release cycle. > To achieve this we need different version for selected subproject therefor we > can't use ${project.version} any more. > -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
