>     // 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

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