Subject [jira] [Updated] (HIVE-6469) skipTrash option in hive command line
Date Tue, 20 May 2014 22:55:38 GMT

     [ https://issues.apache.org/jira/browse/HIVE-6469?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.

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.
