Reid Chan created HBASE-22861:
---------------------------------
Summary: [WAL] Merged region should get its WAL according to
WALProvider.
Key: HBASE-22861
URL: https://issues.apache.org/jira/browse/HBASE-22861
Project: HBase
Issue Type: Bug
Reporter: Reid Chan
This one is similar to HBASE-22774.
Merging regions works fine by default because all regions shared one wal. But
if multiwal is enabled, merged region should get its wal according to strategy.
{code:title=HRegion.java|borderStyle=solid}
HRegion createMergedRegionFromMerges(final HRegionInfo mergedRegionInfo,
final HRegion region_b) throws IOException {
HRegion r = HRegion.newHRegion(this.fs.getTableDir(),
this.getWAL(), // Here should use rsService.getWAL(mergedRegionInfo),
then wal provider and strategy if there is will take effect.
fs.getFileSystem(), this.getBaseConf(), mergedRegionInfo,
this.getTableDesc(), this.rsServices);
...
return r;
}
{code}
