And one of the good things about open-source projects like Hadoop, you can
read all about why :-) : https://issues.apache.org/jira/browse/HADOOP-4952
Enjoy!

Hi Doris!
FileContext was created to overcome some of the limitations that we learned

I suspect FileContext is probably the interface you want to use.
