Rename Row-Key to Hbase

I have a table client in production. Now I want to rename the rowkey from "timestamp" to "SSN timestamp". How can I do the same? Is there an alter command to change existing line keys, or is there another way?

Hbase data saved in hdf. Since hdfs blocks cannot be updated, you cannot update cells in hbase. An update is one delete and one new insert. You can write a map to reduce to scan, delete and insert all lines. Then do a large seal to clear the marked lines for deletion.
