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

             Summary: Large compilation unit tests fails due to high memory allocation
                 Key: DRILL-1808
                 URL: https://issues.apache.org/jira/browse/DRILL-1808
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Steven Phillips


The buildSchema method of external sort calls allocateNew() on each vector in schema batch,
which normally isn't much memory, but when there are thousands of columns, this ends up being
significant. We should avoid allocating any memory for the schema batch.
