Question

As we know, hbase has a feature that a specific Row and specific Column can record recent change values by timestamps.
So my question is, HOW TO list all the changed values using any HBase command? I googled a lot, but didn’t find any useful links.

Answer 1

You can specify the number of version you get for Scan and Get and it will retrieve them:

 HTable tbl = new HTable(tableName);
 Get q= new Get(Bytes.toBytes(key));
 q.setMaxVersions(numberOfVersionsYouWant);
 Result row= tbl.get(q);
 NavigableMap<byte[],NavigableMap<byte[],NavigableMap<Long,byte[]>>> allVersions=row.getMap();
