kbendick opened a new issue #3453:
URL: https://github.com/apache/iceberg/issues/3453
While testing the 0.12.1 release candidate, I tried running the `add_files`
procedure with an ORC table.
I ran it once, so the files were imported. I then dropped the table, created
a new table, and tried to reimport from the same path.
I got the following `NumberFormatException` when trying to parse the number
of imported files.
```
scala> spark.sql("CALL hive.system.add_files(table => 'hive.default.test2',
source_table => '`orc`.`hdfs://hdfs-box:8020/user/hive/warehouse/orc`')").show
java.lang.NumberFormatException: null

```
The path in the HDFS existed, but there were no files there, so `null`
seems to have been returned as a result.
This seems to still exist in current Iceberg:
https://github.com/apache/iceberg/blob/1c158df94bf004d43867939841e75e4bfb941c16/spark/v3.1/spark/src/main/java/org/apache/iceberg/spark/procedures/AddFilesProcedure.java#L144
We should fail early if there are no files present in the path based
directory (or at least say number of files is zero).
