With 0.23/2.x onwards, to have better behavior, its your Path that will determine the FS in SequenceFile readers/writers. Hence, always make sure your Path carries the proper URI if it is supposed to belong to a different FS. You can look at one of the many Path constructors to help you get such an object.
The change was mainly done to counter situations where a path object belongs to a different FS (has a URI), and a FileSystem object passed along belongs to yet another. To avoid this form of confusion, it was decided to always evaluate the FS out of the Path itself. P.s. (Tip) Use the new Builder API for SequenceFile reader/writer in 0.23/2.x, they are nicer to have. P.p.s. Also, if your question is CDH specific, please always use the cdh-u...@cloudera.org lists instead of the Apache ones.
