Why the metric values are all N/A on the spark webui?

[Akeron-Zhu]

I had run a sql on spark 3.5 with iceberg 1.6.1, as the picture show, the metric values are all N/A except the "number of rows". Did I not configure spark or iceberg properly?

Is this from history server or live driver UI

from history server.

iceberg runtime jar is needed to load iceberg metrics on history server.

Thanks for your reply!
I had check the history server and found that is the root cause of this problem. Now the metrics are showed normally.
