    [ https://issues.apache.org/jira/browse/TEZ-1019?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14294386#comment-14294386 ] 

Hitesh Shah commented on TEZ-1019:
----------------------------------

Yes - if the data turns out to be 0 in size or the initializer realized that there is no data worth reading.
