Navis updated HIVE-3171: ------------------------ Attachment: HIVE-3171.2.patch.txt > Bucketed sort merge join doesn't work when multiple files exist for small > alias > ------------------------------------------------------------------------------- > > Key: HIVE-3171 > URL: https://issues.apache.org/jira/browse/HIVE-3171 > Project: Hive > Issue Type: Bug > Components: Query Processor > Affects Versions: 0.10.0 > Reporter: Joey Echeverria > Assignee: Navis > Labels: bucketing, joins, partitioning > Attachments: HIVE-3171.1.patch.txt, HIVE-3171.2.patch.txt > > > Executing a query with the MAPJOIN hint and the bucketed sort merge join > optimizations enabled: > {noformat} > set hive.input.format=org.apache.hadoop.hive.ql.io.BucketizedHiveInputFormat; > set hive.optimize.bucketmapjoin = true; > set hive.optimize.bucketmapjoin.sortedmerge = true; > {noformat} > works fine with partitioned tables if there is only one partition in the > table. However, if you add a second partition, Hive attempts to do a regular > map-side join which can fail because the tables are too large. Hive ought to > be able to still do the bucketed sort merge join with partitions. -- This message is automatically generated by JIRA.
