Examples of org.apache.hadoop.hbase.NamespaceDescriptor

org.apache.hadoop.hbase.NamespaceDescriptor
Namespace POJO class. Used to represent and define namespaces. Descriptors will be persisted in an hbase table. This works since namespaces are essentially metadata of a group of tables as opposed to a more tangible container.

  @Override
  public NamespaceDescriptor getNamespaceDescriptor(String name) throws IOException {
    if (!isTableNamespaceManagerReady()) {
      throw new IOException("Table Namespace Manager not ready yet, try again later");
    }
    NamespaceDescriptor nsd = tableNamespaceManager.get(name);
    if (nsd == null) {
      throw new NamespaceNotFoundException(name);
    }
    return nsd;
  }
