If you have some free time, can you please review HDFS-1447 ?
HDFS-1447 (Make getGenerationStampFromFile() more efficient, so it doesn't
reprocess full directory listing for every block)

/** Return the disk usage of the filesystem, including total capacity,

public DiskStatus getDiskStatus() throws IOException {
return dfs.getDiskStatus();
}
DistributedFileSystem has the above API from java API side.

HIVE will store the table and hdfs path mappings ralated information in Derby.
I think you can configure other DBs as well but by default Hive supports derby
