Christopher Tubbs commented on ACCUMULO-97:
-------------------------------------------
Maybe we can just increase the default max open files for 1.5.0?
> !METADATA scans could be delayed by regular scans

>
> The tablet server only allows scans to open a max number of files. Once the
> max is reached, scans wait. Its possible that a !METADATA scan could get
> stuck waiting for a long running non !METADATA scan to release files. This
> could slow down the whole system. !METADATA scans wold not starve because a
> fair semaphore is used. However with client timeouts, starvation may be
> possible.
