示例1: initHRegion
import org.apache.hadoop.hbase.regionserver.HRegion; //导入方法依赖的package包/类
Region initHRegion (TableName tableName, String callingMethod,
Configuration conf, Class<?> [] implClasses, byte [][] families)
throws IOException {
HTableDescriptor htd = new HTableDescriptor(tableName);
for(byte [] family : families) {
htd.addFamily(new HColumnDescriptor(family));
}
HRegionInfo info = new HRegionInfo(tableName, null, null, false);
Path path = new Path(DIR + callingMethod);
HRegion r = HRegion.createHRegion(info, path, conf, htd);
// this following piece is a hack.
RegionCoprocessorHost host = new RegionCoprocessorHost(r, null, conf);
r.setCoprocessorHost(host);
for (Class<?> implClass : implClasses) {
host.load(implClass, Coprocessor.PRIORITY_USER, conf);
Coprocessor c = host.findCoprocessor(implClass.getName());
assertNotNull(c);
}
// Here we have to call pre and postOpen explicitly.
host.preOpen();
host.postOpen();
return r;

示例2: initHRegion
import org.apache.hadoop.hbase.regionserver.HRegion; //导入方法依赖的package包/类

// 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.
RegionCoprocessorHost host = new RegionCoprocessorHost(r, null, conf);
