Hm, I got your mind. After looking at the relevant logic,
`customPartitionLocations` will only be used while overwriting hive static
partition.
Thus, we can use `listPartitions` when `partitionsTrackedByCatalog &&
staticPartitions.size < partitionColumns.length` and use `listPartitionNames`
when `partitionsTrackedByCatalog`.
```
if (partitionsTrackedByCatalog) {
if (staticPartitions.size < partitionColumns.length) {
matchingPartitions =
sparkSession.sessionState.catalog.listPartitions(
catalogTable.get.identifier, Some(staticPartitions))
initialMatchingPartitions = matchingPartitions.map(_.spec)
customPartitionLocations = getCustomPartitionLocations(
fs, catalogTable.get, qualifiedOutputPath, matchingPartitions)
} else {
// calling listPartitionNames to find initialMatchingPartitions
}
}
```
