-------------------------------------
Summary: Reading of partitioned table stats slows down explain
Key: HIVE-7655
URL: https://issues.apache.org/jira/browse/HIVE-7655
Project: Hive
Issue Type: Bug
Affects Versions: 0.13.1
Reporter: Mostafa Mokhtar
Assignee: Harish Butani
Fix For: 0.14.0
This defect is due to a regression introduced in
https://issues.apache.org/jira/browse/HIVE-7625, explain for queries that touch
partitioned tables is 10x slower.
RelOptHiveTable.getRowCount calls listPartitionsWithAuthInfo which returns the
data from all partitions, listPartitionsByExpr should be used instead.
