> 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.
