--------------------------------
Summary: Use dummy name for xxxHashMapGenerator key/value schema
field
Key: SPARK-25178
URL: https://issues.apache.org/jira/browse/SPARK-25178
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.0
Reporter: Kris Mok
Following SPARK-18952 and SPARK-22273, this ticket proposes to change the
generated field name of the keySchema / valueSchema to a dummy name instead of
using {{key.name}}.
In previous discussion from SPARK-18952's PR [1], it was already suggested that
the field names were being used, so it's not worth capturing the strings as
reference objects here. Josh suggested merging the original fix as-is due to
backportability / pickability concerns. Now that we're coming up to a new
release, this can be revisited.
