Anoop Sam John commented on HBASE-18145:
----------------------------------------

bq.How about this change? withHeapClose -> closeHeapAndCachedScanners
withDelayedScannersClose?
May be we need just one List for this scanners to be delayed closed? (deferred closed).. 
   Like below?
private final List<KeyValueScanner> scannersForDelayedClose = new ArrayList<>();

> After HBASE-17887, the store scanner closes the memstore scanner in updating the inner
scanners. The chunk which stores the current data may be reclaimed. So if the chunk is rewrited
before we send the data to client, the client will receive the corrupt data.
> This issue also breaks the TestAcid*.
