Keith Turner commented on HBASE-5754:
-------------------------------------
In the past we just killed Accumulo processes, the tablet servers, loggers, and
master process(es). We were not looking to test HDFS. For the next release,
Accumulo has moved its write ahead logging to HDFS. So for the next release we
plan to start killing HDFS processes as part of our testing. See ACCUMULO-578,
ACCUMULO-623, and ACCUMULO-636.

> 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.
