> no-arg constructor of /org/apache/hadoop/conf/Configured calls setConf(null). This is
unnecessary and it increases complexity of setConf() code because you have to check for not
null object reference before using it. Under normal conditions setConf() is never called with
null reference, so not null check is unnecessary.
