chunhui shen commented on HBASE-7213:
-------------------------------------
From
{code}
public HLog getWAL(HRegionInfo regionInfo) throws IOException {
//TODO: at some point this should delegate to the HLogFactory
//currently, we don't care about the region as much as we care about the
//table.. (hence checking the tablename below)
if (regionInfo != null &&
Arrays.equals(regionInfo.getTableName(), HConstants.META_TABLE_NAME)) {
return getMetaWAL();
}
{code}
what about ROOT region? we put its logs with other user regions?
In MetaServerShutdownHadnler, we consider META and ROOT both are meta regions.
Correct me if wrong
Thanks.
