Hi @yhuai and @JoshRosen, I realised that
https://github.com/apache/spark/pull/13806 is being failed due to this one.
In the case of my PR, it corrects two files in `sql` and `core`. Since it
seems fixing `core` modules triggers all tests by `determine_modules_for_files`.
So, `changed_modules` becomes as below:
```
['root', 'sql']
```
and `dependent_modules` becaomes as below:
```
['pyspark-mllib', 'pyspark-ml', 'hive-thriftserver', 'sparkr', 'mllib',
'examples', 'pyspark-sql']
```
Now, `modules_to_test` does not include `root`, this checking is skipped
but
Both `changed_modules` and `modules_to_test` are being merged below.
This ends up with failing with the message below (e.g.
https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/60990/consoleFull):
```
Error: unrecognized module 'root'. Supported modules: pyspark-core,
pyspark-sql, pyspark-streaming, pyspark-ml, pyspark-mllib
```
