Review comment:
(1)The method `getHadoopConfiguration ` returns `hadoopConfiguration`
that is not null when hadoop path exists but no conf files exist.
(2)The method `getHadoopConfiguration ` returns `hadoopConfiguration` that
is null when hadoop path does not exist.
if hadoopConf == null , hadoop does not exist;
if hadoopConf != null but hadoopConf.size == 0 , hadoop path exists but no
conf files.
