[jira] [Updated] (SPARK-12313) getPartitionsByFilter doesnt handle
predicates on all / multiple Partition Columns
[ https://issues.apache.org/jira/browse/SPARK-12313?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gobinathan SP updated SPARK-12313:
----------------------------------
Description:
When enabled spark.sql.hive.metastorePartitionPruning, the getPartitionsByFilter is used
For a table partitioned by p1 and p2, when triggered hc.sql("select col.... from tabl1 where p1='p1V' and p2= 'p2V' ")
The HiveShim identifies the Predicates and ConvertFilters returns p1='p1V' and col2= 'p2V' .
On these cases the result is not returned. The number of returned rows is always zero.
However, filter on a single column always works. Probalble it doesn't come through this route
