> StoreFlusher.flushSnapshot() mustn't return null value.
> But StripeStoreFlusher.flushSnapshot() does.
> It cause NullPointerException at org.apache.hadoop.hbase.regionserver.HStore.flushCache(HStore.java:802)
> and this makes regions dead after exhaustive retries and no recovery available from it.
> the code (StripeStoreFlusher:64) has to be changed 
> ===============
> from
>     List<Path> result = null 
> to
>      List<Path> result = new ArrayList<Path>();
>  ===============
> to return a empty list not null value.
