Project: HBase
Issue Type: Bug
Components: Compaction
Affects Versions: 0.98.5

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.
