-------------------------------------
Summary: Bucket map join not being selected when bucketed tables
is missing bucket files
Key: HIVE-17939
URL: https://issues.apache.org/jira/browse/HIVE-17939
Project: Hive
Issue Type: Bug
Reporter: Deepak Jaiswal
Assignee: Deepak Jaiswal
Looks like the following logic kicks in during
OpTraitsRulesProcFactory.TableScanRule.checkBucketedTable(), which prevents the
table from being considered a proper bucketed table:
// The number of files for the table should be same as number of
// buckets.
if (fileNames.size() != 0 && fileNames.size() != numBuckets) {
return false;
}
