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

             Summary: Scan, Project, Hash Join do not set container record count
                 Key: DRILL-7325
                 URL: https://issues.apache.org/jira/browse/DRILL-7325
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.16.0
            Reporter: Paul Rogers
            Assignee: Paul Rogers
             Fix For: 1.17.0


See DRILL-7324. The following are problems found because some operators fail to set the record count for their containers.

h4. Scan

TestComplexTypeReader, on cluster setup, using the PojoRecordReader:

ERROR o.a.d.e.p.i.validate.BatchValidator - Found one or more vector errors from ScanBatch
ScanBatch: Container record count not set

Reason: ScanBatch never sets the record count of its container (this is a generic issue, not specific to the PojoRecordReader).

h4. Filter

{{TestComplexTypeReader.testNonExistentFieldConverting()}}:

{noformat}
ERROR o.a.d.e.p.i.validate.BatchValidator - Found one or more vector errors from FilterRecordBatch
FilterRecordBatch: Container record count not set
{noformat}

h4. Hash Join

{{TestComplexTypeReader.test_array()}}:

{noformat}
ERROR o.a.d.e.p.i.validate.BatchValidator - Found one or more vector errors from HashJoinBatch
HashJoinBatch: Container record count not set
{noformat}

Occurs on the first batch in which the hash join returns {{OK_NEW_SCHEMA}} with no records.
