Delete.deleteColumns(family, quantifier)
in Java. However, it is not yet implemented in Clojure-HBase. I have submitted an issue and a pull-request. Before the pull-request is accepted, you can delete a row in the right way like this:
(hb/with-table [ht (hb/table TABLE)] (io! (.delete ht (.deleteColumns (new Delete (tobyte ROWKEY)) (tobyte COLUMNFAMILY) (tobyte COLUMNQUANTIFIER)))))
DON'T DO
I did something stupid like calling:(hb/with-table [ht (hb/table TABLE)] (hb/delete ROWKEY :with-timestamp-before 3000000000 ; DON'T TO THIS [[:column CF CQ]]))In fact, HBase inserts a DELETE mark with the timestamp, meaning that you can no longer put a new value before it is expired.
