Paul Rogers created DRILL-7325:
----------------------------------
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.
