[jira] [Created] (ACCUMULO-3359) FileManager.reserverReaders provides no pooling for meta table files

John Vines created ACCUMULO-3359:
------------------------------------

             Summary: FileManager.reserverReaders provides no pooling for meta table files
                 Key: ACCUMULO-3359
                 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.
