failed to get create batch op metadata: %w

Error message

failed to get create batch op metadata: %w

What it means

op.Metadata() failed to fetch the long-running operation's metadata after CreateBatch succeeded — the operation may have already been deleted, or the metadata lookup hit a transient API error.

Solutions

1. Retry batch creation; metadata retrieval is occasionally transient
2. Check that the operation still exists in the Dataproc console
3. Inspect the wrapped error for the underlying gRPC status
