Robert Hou created DRILL-5374: --------------------------------- Summary: Parquet filter pushdown does not prune partition with nulls when predicate uses float column Key: DRILL-5374 URL: https://issues.apache.org/jira/browse/DRILL-5374 Project: Apache Drill Issue Type: Bug Components: Query Planning & Optimization Affects Versions: 1.9.0 Reporter: Robert Hou Assignee: Jinfeng Ni
Drill does not prune enough partitions for this query when filter pushdown is used with metadata caching. The float column is being compared with a double value. {code} 0: jdbc:drill:zk=10.10.100.186:5181/drill/rho> select count(*) from orders_parts_metadata where float_id < 1100.0; {code} To reproduce the problem, put the attached files into a directory. Then {code} create the metadata: refresh table metadata dfs.`path_to_directory`; {code} For example, if you put the files in /drill/testdata/filter/orders_parts_metadata, then run this sql command {code} refresh table metadata dfs.`/drill/testdata/filter/orders_parts_metadata`; {code} -- This message was sent by Atlassian JIRA (v6.3.15#6346)
