-------------------------------------

             Summary: Add a system stress test based on key/cell/row size
                 Key: ACCUMULO-2789
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2789
             Project: Accumulo
          Issue Type: Improvement
          Components: test
            Reporter: Sean Busbey
            Assignee: Sean Busbey
            Priority: Minor
             Fix For: 1.5.2, 1.6.1, 1.7.0


Add a system test that allows stress testing an Accumulo instance in the presence of large
cells and rows.

The test should run a configurable number of ingest and reading clients and allow setting:

* configurable range of overall key size
* configurable range of key component sizes
* configurable value size
* configurable number of cells per row
* optional use of isolation on server and/or client

This kind of test would help us preemptively find issues like ACCUMULO-2671, ACCUMULO-201,
and the tserver memory crashes observed with some large mutation sizes while working on YCSB
support for Accumulo.

It will also help us provide test examples of supporting large cardinality on rowids, column
families, and visibilities.
