> I have made some changes to the alter operation on the hbase shell.
> Now we can add, update, delete the column families. Also, make the
> changes to the TableHandler in REST interface.
> changes to the hbase shell:
> > alter 'table', {NAME => 'cf', VERSIONS => 3}
> This command will try to find the column family named 'cf' at first.
> If has, it will modifyColumn, if not, add the column
> > alter 'table', {NAME => 'cf', 'method' => 'delete'}
> This command will delete the column family named 'cf'.
> To achieve this goal,  i also add a method to the HBaseAdmin.java
> public TableDescriptor getTableDescriptor(byte[] tableName);
> changes to the TableHandler in REST interface.
> > curl -X PUT -T - http://localhost:60050/api/tablename
> <?xml version="1.0" encoding="UTF-8"?>
> <table>
>  <name>tables</name>
>  <columnfamilies>
>    <columnfamily>
>      <name>cf1</name>

>      <in-memory>false</in-memory>
>      <block-cache>true</block-cache>
>    </columnfamily>

> It will check the column family 'cf1'. If exists, modifyColumn, if
> not,  addColumn
> > curl -X DELETE http://localhost:60050/api/tablename?column=cf1
> It will deleteColumn 'cf1'.
