Kevin Wilfong created HIVE-3899:
-----------------------------------
Summary: Partition pruning fails on <constant> = <constant>
expression
Key: HIVE-3899
URL: https://issues.apache.org/jira/browse/HIVE-3899
Project: Hive
Issue Type: Bug
Components: Metastore, Query Processor
Affects Versions: 0.11.0
Reporter: Kevin Wilfong
Assignee: Kevin Wilfong
When a query has a filter that is the conjunction of only
<partition_column> = <string constant>
and
<string constant> = <string constant>
The whole filter will be passed to the metastore's get_partitions_by_filter
method. The grammar used to parse the filter only supports filters where one
side is a column, so it fails on the <constant> = <constant> expression.
These should be caught in the checkJDOPushDown method in the Utilities class.
