Xiaomeng Zhang updated HIVE-23717:
----------------------------------
Description:
External + purge tables are more backward compatible with the old managed
tables.
Applications can use a HS2 URL that sets the session level property for default
table type to external-purge tables to be true.
As part of this we need a notion of a "session level only" config parameter(s).
Adding a new jdbc config: *hiveCreateAsExternalLegacy*, a hs2 config
*hive.create.as.external.legacy*, when set to true, create external purge table
by default.
Adding *MANAGED* keyword. "create managed table" will create table based on
hive.create.as.acid and hive.craete.as.insert.only values, not impacted by the
new config.
