[jira] [Commented] (AMBARI-2880) null property values generated during Hadoop 1 stack install

["Srimanth Gunturi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-2880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13737674#comment-13737674 ] 

Srimanth Gunturi commented on AMBARI-2880:
------------------------------------------

Problem was that App.isHadoopStack() always returns true - even when Hadoop 1.x stack is selected. This is due to some changes made for mock data.
