Tsz Wo (Nicholas), SZE commented on HDFS-3388:
----------------------------------------------

- Since GetJournalEditServletFaultInjector is an inner class, let's simply call 
it FaultInjector.

- GetJournalEditServletFaultInjector.getInstance() is not used (and it should 
be static if you want to use it.)

- change 
{code}
new String(path1.toString() + "/current")
{code}
to 
{code}
"path1 + "/current"
{code}

                
> GetJournalEditServlet should catch more exceptions, not just IOException

> GetJournalEditServlet has the same problem as that of GetImageServlet 
> (HDFS-3330). It should be fixed in the same way. Also need to make 
> CheckpointFaultInjector visible for journal service tests.
