In the docs at http://druid.io/docs/0.6.146/Tasks.html the kill task says that
Killable segments must be disabled (used==0) in the Druid segment table.
I looked around the docs but couldn’t find any way via druid to do that. One obvious way is direct DB access. Is there any cleaner way to change this flag? I mean there should not be a need for directly interacting with druid’s internal tables.
