Subject [jira] [Commented] (HIVE-13223) HoS may hang for queries that run on 0 splits
Date Fri, 08 Apr 2016 19:04:25 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15232725#comment-15232725
] 

Ashutosh Chauhan commented on HIVE-13223:
-----------------------------------------

HIVE-13040 has two changes. One is to not generate 0-length files when its known that they
don't contain any data and other is to skip 0-length file while generating splits. This second
change may result in a job which has no split e.g. when buckets are empty. For exact repro,
you may run any of the failures reported by HiveQA here, e.g. orc_merge5,orc_merge6,vector_outer_join1,vector_outer_join4
etc.
