Subject [jira] [Commented] (YARN-178) Fix custom ProcessTree instance creation
Date Tue, 23 Oct 2012 10:57:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-178?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13482256#comment-13482256

Radim Kolar commented on YARN-178:

you need constructor which is shared by all subclasses. Alternatively, it could be method
instead of constructor but because root process pid do not change then constructor is better.
