Summary: Support Complex Hive Schema's
Key: HAWQ-1265
URL: https://issues.apache.org/jira/browse/HAWQ-1265
Project: Apache HAWQ
Issue Type: Improvement
Components: Hcatalog, PXF
Reporter: Michael Andre Pearce (IG)
Assignee: Ed Espino
Currently if in hive you have Avro or other formats, where the schema is
complex, you cannot currently query the fields in the complex object via
hcatalog/pxf integration.
In terms of Avro Schema - records, enums and complex arrays, do not work.
Hive fully supports this complex/object notation, as does many of the other SQL
tools in the Hadoop eco-system (Spark, Impala, Drill).
These all seem to support the same styled solution of using dots for complex
object/path negation:
SELECT schema.table.fieldA.nestedRecordFieldS FROM myavrotable;
