>
> When Drillbit dies or was killed, the running queries might be hang there,
> and the sqlline would also hang there. There are two cases:
> 1. The Drillbit having the foreman dies, or the foreman thread dies, but the
> rest of non-root fragments are still running, even though the connection
> between the client and the foreman has been lost.
> 2. The Drillbit running the non-root fragments dies, but foreman and other
> non-root fragments are still running.
> In either cases, Drill should have a way to detect such node failure, and
> cancel the running queries, and return to a state where client could submit a
> new query, or re-connect (if connection is lost in case foreman dies) to a
> different foreman.
