[jira] [Updated] (TEZ-969) Hive on Tez job gets stuck as reducers makes no progress

     [ https://issues.apache.org/jira/browse/TEZ-969?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Siddharth Seth updated TEZ-969:
-------------------------------

    Attachment: TEZ-969.1.txt

Patch changes the static field to a non-static. Not removing it for now - will leave that for a later patch, if at all.
Also returns an EmptyIterator in case the merger is called with an empty segment list.
