--------------------------------------
Summary: MaterializedField equality doesn't check if nested fields
are equal
Key: DRILL-3487
URL: https://issues.apache.org/jira/browse/DRILL-3487
Project: Apache Drill
Issue Type: Bug
Components: Metadata
Reporter: Steven Phillips
Assignee: Hanifi Gunes
In several places, we use BatchSchema.equals() to determine if two schemas are
the same. A BatchSchema is a set of MaterializedField objects. But ever since
DRILL-1872, the child fields are no longer checked.
What this means, essentially, is that BatchSchema.equals() is not valid for
determining schema changes if the batch contains any nested fields.
