Hanifi Gunes commented on DRILL-1435:
-------------------------------------

More on concurrency: disabling producer consumer seems to eliminate the issue.

> When I query a psv file with limit, sqlline frequently hangs. It sometimes comes back
after a while but most of the time, it just hangs. When it hangs, I saw the InterruptedException
in drill bit.log.
