Ted Yu commented on HBASE-10017:
--------------------------------
Here is the command Hadoop QA used for site generation:
{code}
$MVN compile site -DskipTests -D${PROJECT_NAME}PatchProcess >
$PATCH_DIR/patchSiteOutput.txt 2>&1
{code}
Did it work for you ?
What OS do you use ?
On Mac, I got:
{code}
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-site-plugin:3.3:site (default-site) on project
hbase: Error during page generation: Error rendering Maven report:

> Key: HBASE-10017
> URL: https://issues.apache.org/jira/browse/HBASE-10017
> Project: HBase
> Issue Type: Bug
> Components: mapreduce
> Affects Versions: 0.94.6
> Reporter: Roman Nikitchenko
> Priority: Critical
> Attachments: HBASE-10017-r1544633.patch, HBASE-10017-r1544633.patch

>
> Inside HRegionPartitioner class there is getPartition() method which should
> map first numPartitions regions to appropriate partitions 1:1. But based on
> condition last region is hashed which could lead to last reducer not having
> any data. This is considered serious issue.
> I reproduced this only starting from 16 regions per table. Original defect
> was found in 0.94.6 but at least today's trunk and 0.91 branch head have the
> same HRegionPartitioner code in this part which means the same issue.
