>                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3359
>             Project: Accumulo
>          Issue Type: Bug
>          Components: tserver
>            Reporter: John Vines
>
> We have tserver.scan.files.open.max, which can be used to control how many files we open at scan time. If we have several long running queries, this can cause starvation of operations reading the metadata / root tables that we should try to prevent.
