Wechar updated HIVE-27266:
--------------------------
Description:
Followed HIVE-19783, we only need partNames instead of partName and location
pairs if we do not need check location.
We add a new benchmark *dropTableMetadataWithPartitions* to delete only
metadata rather than the real table data.
Test results like:
* Before the patch:
{code:bash}
Operation Mean Med Min Max Err%
dropTableMetaOnlyWithPartitions.10 23.70 21.87 19.36 31.73 14.48
dropTableMetaOnlyWithPartitions.100 54.42 54.15 45.92 76.68 8.891
dropTableMetaOnlyWithPartitions.1000 462.5 456.1 321.0 654.3 15.96
{code}
* After the patch:
{code:bash}
Operation Mean Med Min Max Err%
dropTableMetaOnlyWithPartitions.10 21.49 21.24 19.30 27.90 6.661
dropTableMetaOnlyWithPartitions.100 51.51 48.30 44.86 85.23 16.91
dropTableMetaOnlyWithPartitions.1000 415.4 407.2 308.8 595.2 14.28
{code}
