Apropos, on {{dropTable()}} and {{dropPartition()}}, table data is deleted directly (and not moved to trash) if the following hold true: > # The table is MANAGED. > # The {{deleteData}} parameter to the {{HMSC.drop*()}} methods is true. > # Either PURGE is explicitly specified on the command-line (or rather, {{"ifPurge"}} is set in the environment context, OR > # TBLPROPERTIES contains {{"auto.purge"="true"}} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
