示例1: preDelete

import org.apache.hadoop.hbase.client.Delete; //导入方法依赖的package包/类
@Override
public void preDelete(final ObserverContext<RegionCoprocessorEnvironment> c,
    final Delete delete, final WALEdit edit, final Durability durability)
    throws IOException {
  // An ACL on a delete is useless, we shouldn't allow it
  if (delete.getAttribute(AccessControlConstants.OP_ATTRIBUTE_ACL) != null) {
    throw new DoNotRetryIOException("ACL on delete has no effect: " + delete.toString());
  }
  // Require WRITE permissions on all cells covered by the delete. Unlike
  // for Puts we need to check all visible prior versions, because a major
  // compaction could remove them. If the user doesn't have permission to
  // overwrite any of the visible versions ('visible' defined as not covered
  // by a tombstone already) then we have to disallow this operation.
  RegionCoprocessorEnvironment env = c.getEnvironment();
  Map<byte[],? extends Collection<Cell>> families = delete.getFamilyCellMap();
  User user = getActiveUser();
  AuthResult authResult = permissionGranted(OpType.DELETE, user, env, families, Action.WRITE);
  logResult(authResult);
  if (!authResult.isAllowed()) {
    if (cellFeaturesEnabled && !compatibleEarlyTermination) {
      delete.setAttribute(CHECK_COVERING_PERM, TRUE);
    } else if (authorizationEnabled) {
      throw new AccessDeniedException("Insufficient permissions " +
        authResult.toContextString());
    }
  }
}
