cluster.DefaultSubmitArgs is now deprecated. It used to be prepended to
spark_submit Tool calls, but since 7920dc9 the spark-submit builder
constructs argv from the structured fields in the tool call. The field is
still accepted by the admin API and still persisted to the DB, so this is
a non-breaking change.
This commit deliberately does NOT remove:
- the Cluster.DefaultSubmitArgs field in internal/cluster/types.go
- the default_submit_args DB column
- the admin API read/write support in internal/admin/router.go
- existing storage/repo tests
Runtime now logs a one-time slog.Info when the PUT handler receives a
non-empty default_submit_args value, warning operators that the field is
ignored by spark_submit and that they should use spark_conf / extra_args
instead.
Follow-up removal should touch:
- the Cluster struct field and its JSON tag
- storage/cluster_repo.go scan/insert/update SQL and params
- admin/router.go JSON round-tripping
- storage/cluster_repo_test.go assertions
- the DB migration dropping the default_submit_args column
