Ravi Prakash updated HIVE-6469:
-------------------------------
Description:
Th current behavior of hive metastore during a "drop table <table_name>"
command is to delete the data from HDFS warehouse and put it into Trash.
Currently there is no way to provide a flag to tell the warehouse to skip trash
while deleting table data.
This ticket is to add skipTrash configuration "hive.warehouse.data.skipTrash" ,
which when set to true, will skipTrash while dropping table data from hdfs
warehouse. This will be set to false by default to keep current behavior.
This would be good feature to add, so that an admin of the cluster can specify
when not to put data into the trash directory (eg. in a dev environment) and
thus not to fill hdfs space instead of relying on trash interval and policy
configuration to take care of disk filling issue.
