Jayesh updated HIVE-6469:
-------------------------
Description:
current behavior of hive metastore is "drop table <table_name>" command deletes
the data from HDFS warehouse and puts it into Trash.
Currently there is no way to provide flag to tell 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 ll be set to false by default to keep current behavior.
This would be good feature to add, so that user can specify when not to put
data into trash directory and thus not to fill hdfs space instead of relying on
trash interval and policy configuration to take care of disk filling issue.
was:
hive drop table command deletes the data from HDFS warehouse and puts it into
Trash.
Currently there is no way to provide flag to tell warehouse to skip trash while
deleting table data.
This ticket is to add skipTrash feature in hive command-line, that looks as
following.
hive -e "drop table skipTrash testTable"
This would be good feature to add, so that user can specify when not to put
data into trash directory and thus not to fill hdfs space instead of relying on
trash interval and policy configuration to take care of disk filling issue.
