You need to insert a cell with a specific timestamp (version) 13353903160532. Which of the
following is true?
The timestamp for the entire row must be updated to 13353903160532
The Put class allows setting a cell specific timestamp
The Put class allows setting a column family-specific timestamp
The HTable class allows you to temporarily roll back the newer versions of the cell
Doing a put always creates a new version of a cell, at a certain timestamp. By
default the system uses the server’s currentTimeMillis, but you can specify the version (= the long
integer) yourself, on a per-column level. This means you could assign a time in the past or the
future, or use the long value for non-time purposes.
To overwrite an existing value, do a put at exactly the same row, column, and version as that of
the cell you would overshadow.
