Subject [jira] [Commented] (HBASE-15811) Batch Get after batch Put does not fetch all Cells
Date Thu, 12 May 2016 16:38:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15811?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15281712#comment-15281712

Elliott Clark commented on HBASE-15811:

If this is dependent on data size then I would start to look at the batching logic in the
client side.

> 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.
