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

             Summary: Some functional tests are failing because sort limit is too low
                 Key: DRILL-4253
                 URL: https://issues.apache.org/jira/browse/DRILL-4253
             Project: Apache Drill
          Issue Type: Test
          Components: Tools, Build & Test
    Affects Versions: 1.5.0
         Environment: 4 nodes cluster, 32 cores each
            Reporter: Deneche A. Hakim


The following tests are running out of memory:
{noformat}
framework/resources/Functional/data-shapes/wide-columns/5000/1000rows/parquet/q174.q
framework/resources/Functional/data-shapes/wide-columns/5000/1000rows/parquet/q171.q

framework/resources/Functional/data-shapes/wide-columns/5000/1000rows/parquet/q163_DRILL-2046.q
{noformat}

With errors similar to the following:
{noformat}
java.sql.SQLException: SYSTEM ERROR: DrillRuntimeException: Failed to pre-allocate memory for SV. Existing recordCount*4 = 0, incoming batch recordCount*4 = 696
{noformat}

{noformat}
Unable to allocate sv2 for 1000 records, and not enough batchGroups to spill.
{noformat}

Those queries operate on wide tables and the sort limit is too low when using the default value for {{planner.memory.max_query_memory_per_node}}.

We should update those tests to set a higher limit (4GB worked well for me) to {{planner.memory.max_query_memory_per_node}}
