Description

TableModifyFamilyHandler:
  protected void handleTableOperation(List<HRegionInfo> regions) throws IOException {
    // Update table descriptor in HDFS
    HTableDescriptor htd =
      this.masterServices.getMasterFileSystem().modifyColumn(tableName, familyDesc);
    // Update in-memory descriptor cache
    this.masterServices.getTableDescriptors().add(htd); // 2
  }
MasterFileSystem:
  public HTableDescriptor modifyColumn(byte[] tableName, HColumnDescriptor hcd)
      throws IOException {
    this.services.getTableDescriptors().add(htd); // 1
    return htd;
  }

The FSTableDescriptors.add(HTableDescriptor htd) is called twice, we should remove one.
