Subject [jira] [Commented] (HAMA-405) NoClassDefFoundError: org/apache/commons/cli/ParseException running bin/hama zookeeper
Date Wed, 22 Jun 2011 22:56:47 GMT

    [ https://issues.apache.org/jira/browse/HAMA-405?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13053520#comment-13053520

Joseph Boyd commented on HAMA-405:
----------------------------------

While looking into this, I suspect the problem was introduced in HAMA-402 , where several
dependencies were removed from the advice of the 'mvn dependency:analyze' report.

The report is correct, hama doesn't depend on those item, but instead has a transitive dependency
on them. As one example, commons-cli jar, referenced in the error in the description, is required
by hadoop-core, not by hama.
