-----------------------------
Description:
Example as:
CREATE TABLE src (key string, value string) TBLPROPERTIES ('LIFECYCLE'='50d');
-- alter table src and reset it's lifecycle as 50 day
-- alter 50 days the table will be dropped automatically
ALTER TABLE src SET TBLPROPERTIES('LIFECYCLE'='50d');
-- alter specific table partition's lifecycle
-- we have DBPROPERTIES and TBLPROPERTIES , but seems we do not have 'PRTPROPERTIES'
ALTER TABLE srcpart PARTITION (dt='20130614',hr='10') SET PRTPROPERTIES('LIFECYCLE'='50d');
