Subject [jira] [Commented] (HBASE-18145) The flush may cause the corrupt data for reading
Date Fri, 02 Jun 2017 04:41:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18145?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16034120#comment-16034120

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

Very imp finding.. 
In shipped() new call to clearAndClose(scannerForDelayedClose);,  We should do this after
prevCell clone.  That is better as there is no chance at all that prevCell belong to this
scanner which is getting closed now.
clearAndClose(scannerForDelayedClose);  call in close()  ->  Looks ok to do this whatever
be the boolean param.  Still it might be better to double check.  May be best would be follow
the other list close way of whether boolean true, then only close here. After shipped() call
any way close is there. WDYT?   We have to change the param name in that case 
bq.close(boolean withHeapClose)

> 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*.
