HRegion reopenRegion(final HRegion closedRegion, Class<?> ... implClasses) throws IOException { //RegionInfo info = new RegionInfo(tableName, null, null, false); HRegion r = HRegion.openHRegion(closedRegion, null); // this following piece is a hack. currently a coprocessorHost // is secretly loaded at OpenRegionHandler. we don't really // start a region server here, so just manually create cphost // and set it to region. Configuration conf = TEST_UTIL.getConfiguration(); RegionCoprocessorHost host = new RegionCoprocessorHost(r, Mockito.mock(RegionServerServices.class), conf); r.setCoprocessorHost(host); for (Class<?> implClass : implClasses) { host.load((Class<? extends RegionCoprocessor>) implClass, Coprocessor.PRIORITY_USER, conf); } // we need to manually call pre- and postOpen here since the // above load() is not the real case for CP loading. A CP is // expected to be loaded by default from 1) configuration; or 2) // HTableDescriptor. If it's loaded after HRegion initialized, // the pre- and postOpen() won't be triggered automatically. // Here we have to call pre and postOpen explicitly. host.preOpen(); host.postOpen(); return r; }
