["Mona Chitnis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OOZIE-860?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13396169#comment-13396169 ] 

Mona Chitnis commented on OOZIE-860:
------------------------------------

There can only be a single <start-instance> and a single <end-instance> tag to mark the synchronous dataset range. 'handleExpressionWithMultipleInstances' will not output the correct error message for this. Consider accounting for it in that method or writing separate error messages directly in your code block.

> it would be nice to implement the check to error out at job submission
