示例1: getConnectionForEnvironment

import org.apache.hadoop.hbase.coprocessor.RegionCoprocessorEnvironment; //导入方法依赖的package包/类
/**
 * Create an unmanaged {@link HConnection} based on the environment in which we are running the
 * coprocessor. The {@link HConnection} must be externally cleaned up (we bypass the usual HTable
 * cleanup mechanisms since we own everything).
 * @param env environment hosting the {@link HConnection}
 * @return an unmanaged {@link HConnection}.
 * @throws IOException if we cannot create the connection
 */
public static ClusterConnection getConnectionForEnvironment(CoprocessorEnvironment env)
    throws IOException {
  // this bit is a little hacky - just trying to get it going for the moment
  if (env instanceof RegionCoprocessorEnvironment) {
    RegionCoprocessorEnvironment e = (RegionCoprocessorEnvironment) env;
    RegionServerServices services = e.getRegionServerServices();
    if (services instanceof HRegionServer) {
