> -----------------------------------------------------------------------------------------------------
>
> Key: HBASE-12235
> URL: https://issues.apache.org/jira/browse/HBASE-12235
> Project: HBase
> Issue Type: Task
> Components: test
> Affects Versions: 0.94.0
> Environment: 0.94.15 compiled with jdk6 running on jdk7 (but I don't
> think it's relevant)
> Reporter: Sean Busbey
> Assignee: Sean Busbey
> Priority: Minor
> Fix For: 0.94.25
>
> Attachments: HBASE-12235-0.94.1.patch.txt
>
>
> I had TestDistributedLogSplitting.testRecoveredEdits fail on a internal test
> rig. It's very infrequent.
> The proximal failure looks like HBASE-9002, the assertion finds 0 edits
> instead of 1000.
> Looking through the logs, the #regions printed is 1
> {code}
> line 236 LOG.info("#regions = " + regions.size());
> {code}
> And then in the makeHLog method I never see any log entry for the actual
> writing
> {code}
> line 569 for (int i = 0; i < n; i++) {
> line 570 LOG.info("region " + hris.get(i).getRegionNameAsString() + "
> has " + counts[i] + " edits");
> line 571 }
> {code}
> I think what's happening is we're picking a region that is META or ROOT, so
> the checks after the "#regions=" line removes the region and we end up
> inserting no data.
> It looks like the patch for HBASE-9002 should fix this.
