Checked master branch and branch-2.x.
They look good, because wal is got from {{rs.getWAL(regionInfo)}}
{code:title=AssignRegionHandler.java|borderStyle=solid}
try {
TableDescriptor htd =
tableDesc != null ? tableDesc :
rs.getTableDescriptors().get(regionInfo.getTable());
if (htd == null) {
throw new IOException("Missing table descriptor for " + regionName);
}
// pass null for the last parameter, which used to be a
CancelableProgressable, as now the
// opening can not be interrupted by a close request any more.
region = HRegion.openHRegion(regionInfo, htd, rs.getWAL(regionInfo),
rs.getConfiguration(),
rs, null);
} catch (IOException e) {
cleanUpAndReportFailure(e);
return;
}

I added {{Performance}} component.
Multiwal can boost performance up. But w/o this patch, the performance gain
will lose since daughter regions inherit their parent's wal which back to the
default pattern (multiple regions share one wal).

> Project: HBase
> Issue Type: Bug
> Components: wal
>Affects Versions: 1.4.6
>Reporter: Reid Chan
>Assignee: Reid Chan
>Priority: Major
>
> Having {{hbase.wal.provider}} set {{multiwal}}, it works fine on regionserver
> restart, at the beginning.
> But when region split happened, those daughter regions would inherit her
> parent's WAL, which violates the setting. For example, when
> {{hbase.wal.regiongrouping.strategy}} set {{identity}}, each daughter regions
> should create its own WAL instead of inheriting.

The fix is easy, but it breaks UTs which are pretty hard to fix. I'm still
working on it.
