Ian Varley resolved HBASE-5754.

> Key: HBASE-5754
> URL: https://issues.apache.org/jira/browse/HBASE-5754
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.92.1
> Environment: 10 node test cluster
> Reporter: Eric Newton
> Assignee: stack
>
> Keith Turner re-wrote the accumulo continuous ingest test using gora, which has both hbase and accumulo back-ends.
> I put a billion entries into HBase, and ran the Verify map/reduce job. The verification failed because about 21K entries were missing. The goraci [README|https://github.com/keith-turner/goraci] explains the test, and how it detects missing data.
> I re-ran the test with 100 million entries, and it verified successfully.
> Both of the times I tested using a billion entries, the verification failed.
> If I run the verification step twice, the results are consistent, so the problem is
> probably not on the verify step.
> Here's the versions of the various packages:
> ||package||version||
> |hadoop|0.20.205.0|
> |hbase|0.92.1|
> |gora|http://svn.apache.org/repos/asf/gora/trunk r1311277|
> |goraci|https://github.com/ericnewton/goraci tagged 2012-04-08|
> The change I made to goraci was to configure it for hbase and to allow it to build properly.
