I can't get many versions of the specified column,but only get the latest
version of the specified column. Is there anyone help me?
//put data by version
final Put p = new Put(key); // key
final long ts = System.currentTimeMillis();
p.add(FAMILY, q1, ts,v1);
p.add(FAMILY, q2, ts,v2);
p.add(FAMILY, q3, ts,v3);
table.put(p);
//get all versions of data
final Get get = new Get(key);
get.addFamily(FAMILY);
get.setMaxVersions(10);
final Result result = htable.get(get);
final NavigableMap<byte[], NavigableMap<byte[],
NavigableMap<Long, byte[]>>> map = result.getMap();
final Set<Entry<byte[], NavigableMap<byte[],
NavigableMap<Long, byte[]>>>> entrySet = map.entrySet();
final Iterator<Entry<byte[], NavigableMap<byte[],
NavigableMap<Long, byte[]>>>> iterator = entrySet
.iterator();
while (iterator.hasNext())
{
final Entry<byte[], NavigableMap<byte[],
NavigableMap<Long, byte[]>>> next = iterator.next();
System.out.println(Bytes.toString(next.getKey())); //family
for (final Entry<byte[], NavigableMap<Long, byte[]>>
item : next.getValue().entrySet())
{
System.out.println(Bytes.toString(item.getKey()));
for (final Entry<Long, byte[]> _item :
item.getValue().entrySet())
{
System.out.println(_item.getKey()); //q
System.out.println(Bytes.toString(_item.getValue()));
//value
}
}
}
