URL: https://github.com/apache/hadoop/pull/3351#issuecomment-915436686
If we want to add support dynamic/variable partition numbers, we need to
modify this function as well in INode.java.
idx here is the partition id. it is modulo by INodeMap.NUM_RANGES_STATIC.
```
public static long indexOf(long[] key) {
if(key[key.length-1] == INodeId.ROOT_INODE_ID) {
return key[0];
}
long idx = LARGE_PRIME * key[0];
idx = (idx ^ (idx >> 32)) & (INodeMap.NUM_RANGES_STATIC -1);
return idx;
}
```
