>
> HBaseAdmin.mergeRegions() calls HBaseAdmin.getRegion() internally.
> HBaseAdmin.getRegion() requires the full region name. So
> MetaTableAccessor.getRegion always returns null and this causes one more meta
> table scan.
> {code}
> Pair<HRegionInfo, ServerName> getRegion(final byte[] regionName) throws
> IOException {
> if (regionName == null) {
> throw new IllegalArgumentException("Pass a table name or region name");
> }
> Pair<HRegionInfo, ServerName> pair =
> MetaTableAccessor.getRegion(connection, regionName);
> if (pair == null) {
> {code}
> I suppose to use full region names instead of encoded region names in
> HBaseAdmin.mergeRegions().
