In HiveConf.java, the description is: "Whether to push predicates down into storage handlers. Ignored when hive.optimize.ppd is false" which seems to be an incorrect description for this property. Would something like "When hive.optimize.ppd is true, removes duplicate filters from the query plan. Set this to false if it filters too aggressively." be more accurate? > FilterOperator is applied twice with ppd on. > -------------------------------------------- > > Key: HIVE-1538 > URL: https://issues.apache.org/jira/browse/HIVE-1538 > Project: Hive > Issue Type: Bug > Components: Query Processor > Reporter: Amareshwari Sriramadasu > Assignee: Amareshwari Sriramadasu > Fix For: 0.8.0 > > Attachments: patch-1538-1.txt, patch-1538-2.txt, patch-1538-3.txt, patch-1538-4.txt, patch-1538.txt > > > With hive.optimize.ppd set to true, FilterOperator is applied twice.
