Description

Consider the following:

Configuration conf1 = new Configuration();
FileSystem fs1 = FileSystem.get(conf1); //conf1 may be modified, the cache key stored will use the modified values.

Configuration conf2 = new Configuration(); //create another conf, which won't have the modified values.
FileSystem fs2 = FileSystem.get(conf2); //may initialize another FileSystem instead of returning the cached FileSystem, since conf2 does not have the modified values initially.

Therefore, FileSystem.get(conf) may keeps creating FileSystem and replaces the cached one.
