[jira] [Commented] (UIMA-4880) DUCC JobDriver doesn't terminate when fewer than expected work-items found

["Lou DeGenaro (JIRA)" <de...@uima.apache.org>]

    [ https://issues.apache.org/jira/browse/UIMA-4880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15219861#comment-15219861 ] 

Lou DeGenaro commented on UIMA-4880:
------------------------------------

When the Job Driver (JD) detects the following Collection Reader (CR) runtime situation:

1. CR has no more work items, and
2. CR provided work items (if any) have all been processed, and
3. number of  work items processed < total number specified by user

then it will cancel the Job since the total will never be reached!  The Reason on the WS Jobs page will be CanceledByDriver and the hover will display "fewer work items available than total".

> If the CR claims there are 20 work-items but hasNext returns false after 15 then the JobDriver keeps asking for more.  It used to report "Premature" end.
