> We will abort regionserver if memstore flush throws exception.
> I thinks we could do retry to make regionserver more stable because file
> system may be not ok in a transient time. e.g. Switching namenode in the
> NamenodeHA environment
> {code}
> HRegion#internalFlushcache(){
> ...
> try {
> ...
> }catch(Throwable t){
> DroppedSnapshotException dse = new DroppedSnapshotException("region: " +
> Bytes.toStringBinary(getRegionName()));
> dse.initCause(t);
> throw dse;
> }
> ...
> }
> MemStoreFlusher#flushRegion(){
> ...
> region.flushcache();
> ...
> try {
> }catch(DroppedSnapshotException ex){
> server.abort("Replay of HLog required. Forcing server shutdown", ex);
> }
> ...
