[jira] [Commented] (MESOS-6114) ClassNotFoundException shows when
loading java class in framework
[ https://issues.apache.org/jira/browse/MESOS-6114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15562367#comment-15562367 ]
Neil Conway commented on MESOS-6114:
------------------------------------
[~usultrared@gmail.com] -- The error message just indicates that the JVM is unable to find a particular class that your program is using. That by itself is not a Mesos bug. Can you elaborate on how you have configured the JVM you're using for your custom executor? More information about your configuration and environment would be helpful to understand what is going on here.
