Subject [jira] [Commented] (HIVE-13223) HoS may hang for queries that run on 0 splits
Date Fri, 08 Apr 2016 20:55:25 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15232910#comment-15232910

Szehon Ho commented on HIVE-13223:
----------------------------------

We can of course ask, and of course hanging is not a good behavior, but Spark community might
consider a job with 0 splits as invalid.  It has always been not so-great behavior on Hive
side to have empty files in buckets (I guess HIVE-12638 is a similar complaint).

Just to explore the options, is there any JIRA tracking ORC-side fix for handle 0-length files?
