[jira] [Commented] (HIVE-17012) ACID Table: Number of reduce tasks should be computed correctly when sort.dynamic.partition is enabled

    [ https://issues.apache.org/jira/browse/HIVE-17012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16071990#comment-16071990 ] 

Rajesh Balamohan commented on HIVE-17012:
-----------------------------------------

ReducerTraits would be FIXED for ACID tables with buckets. https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/parse/GenTezUtils.java#L102 prevents from computing reducer tasks for Reducer 3.
