Jingcheng Du commented on HBASE-15811:
--------------------------------------
Hi, MultiVersionConsistencyControl has a private lock readWaiters, it only used
in advanceMemstore(WriteEntry e),
{code}
if (nextReadValue > 0) {
synchronized (readWaiters) {
readWaiters.notifyAll();
}
}
{code}
I guess this code is not necessary any more? Or we miss something in somewhere
else?
> Batch Get after batch Put does not fetch all Cells

> Key: HBASE-15811
> URL: https://issues.apache.org/jira/browse/HBASE-15811
> Project: HBase
> Issue Type: Bug
> Components: Client
> Affects Versions: 1.2.1
> Reporter: stack
> Assignee: stack
> Attachments: Test.java, Test2.java
>
>
> A big batch put followed by a batch get does not always return all Cells put.
> See attached test program by Robert Farr that reproduces the issue. It seems
> to be an issue to do with a cluster of more than one machine. Running against
> a single machine does not have the problem (though the single machine may
> have many regions). Robert was unable to make his program fail with a single
> machine only.
> I reproduced what Robert was seeing running his program. I was also unable to
> make a single machine fail. In a batch of 1000 puts, I see one to three Gets
> fail. I noticed too that if I wait a second after a fail and then re-get, the
> Get succeeds.
