Examples with RegionCoprocessorHost org.apache.hadoop.hbase.regionserver.RegionCoprocessorHost used on opensource projects

Example 1 with RegionCoprocessorHost

use of org.apache.hadoop.hbase.regionserver.RegionCoprocessorHost in project hbase by apache.

the class TestCoprocessorInterface method reopenRegion.

Region reopenRegion(final Region closedRegion, Class<?>... implClasses) throws IOException {
    //HRegionInfo info = new HRegionInfo(tableName, null, null, false);
    Region 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, null, conf);
    ((HRegion) r).setCoprocessorHost(host);
    for (Class<?> implClass : implClasses) {
        host.load(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;
