Review Comment:
@deniskuzZ
At present, only one code is involved:
```
// IOPrepareCache.get().allocatePartitionDescMap()
public Map<Map<Path, PartitionDesc>, Map<Path, PartitionDesc>>
allocatePartitionDescMap() {
if (partitionDescMap == null) {
partitionDescMap = new HashMap<>();
}
return partitionDescMap;
}
```
usage demo:
```
// extract all the inputFormatClass names for each chunk in the
// CombinedSplit.
PartitionDesc part =
HiveFileFormatUtils.getFromPathRecursively(pathToPartitionInfo,
inputSplitShim.getPath(0),
IOPrepareCache.get().getPartitionDescMap());
```
