Examples of org.apache.hadoop.hbase.HTableDescriptor.families()

        HashMap<byte[], ColumnDescriptor> columns = new HashMap<byte[], ColumnDescriptor>();
        
        HTable table = getTable(tableName);
        HTableDescriptor desc = table.getMetadata();
        
        for (Entry<Text, HColumnDescriptor> e : desc.families().entrySet()) {
          ColumnDescriptor col = ThriftUtilities.colDescFromHbase(e.getValue());
          columns.put(col.name, col);
        }
        return columns;
      } catch (IOException e) {

              columnEntry.getKey().endsWith(":") ? columnEntry.getKey()
                  : columnEntry.getKey() + ":");


          // get the table descriptor so we can get the old column descriptor
          HTableDescriptor tDesc = getTableDescByName(admin, tableName);
          HColumnDescriptor oldColumnDesc = tDesc.families().get(columnName);


          // combine the options specified in the shell with the options
          // from the exiting descriptor to produce the new descriptor
          columnDesc = getColumnDescriptor(columnName.toString(), columnEntry
              .getValue(), oldColumnDesc);
