HBase：如何将列转换为列，而不是家族列

Question

If possible, can someone give me an example of how to add a column, or columns, to an existing column belonging to an existing column family? I know how to add a column to a column family.

Thanks.

Answer 1

You can put whatever you want in a HBase column: a JSON, a serialized Avro, etc. Simply put under your existing column a more complex structure. But you cannot put another column qualifier under an existing one. You have to respect the table -> column family -> column -> anything structure.
