Subject [jira] [Commented] (HBASE-18145) The flush may cause the corrupt data for reading
Date Fri, 02 Jun 2017 06:53:04 GMT

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

I mean we already have a List of heaps for delayed close..  Now the patch will add a new List
which takes KVScanners. These are memstore scanners..  So I was asking whether these 2 we
can combine into one?

> 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*.
