             Summary: Add FileSystem#closeIfNotReferred method
                 Key: HADOOP-10792
                 URL: https://issues.apache.org/jira/browse/HADOOP-10792
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs
            Reporter: Kousuke Saruta


FileSystem#close closes FileSystem even if the same instance of FileSystem is 
referred by someone.

For instance, a library using FileSystem calls FileSystem.get, and a program 
using the library calls FileSystem.get, both of instances of FileSystem is 
same. 

When the library and the program is implemented as different threads and one 
calls FileSystem.close, another fails most of operations of FileSystem.

So, we need the method like cloesIfNotReferred, which closes FileSystem only if 
a instance of FileSystem is not referred by anyone.
