Fetching and iterating through all column values belonging to all Timestamps of a Row

[Narayanan K]

Hi all,

I am using Hadoop - 0.20.1 and HBASE - 0.20.

Currently, I am trying to retrieve and iterate through all the column values
of a particular rowkey in an Hbase Table.
But I am able to retrieve *only* the cell+value having the *latest Timestamp
*.

Eg:

*hbase>create 'useractivity', 'pageviews'
hbase>put 'useractivity', 'userid1', 'pageviews:uri',
'http://www.allaboutdata.net'
hbase>put 'useractivity', 'userid1', 'pageviews:uri', 'http://www.yahoo.co.in'*

*hbase>get 'useractivity', 'userid1' *
is fetching only the  "http://www.yahoo.co.in"; column value as it has the
latest timestamp.

I wanted to view both the values in the column *uri*.

I tried the same with the java API - Get as well as Scan. But still both of
them gave me the same result with the column having value that was
inserted the latest.
I also read through some old archives and found I could setTimeRange on
Get/Scan which is also not solving my problem.

*get.setTimeRange(0,Long.MAXVALUE);* as in :

 *HTable table = new HTable(new HBaseConfiguration(), "useractivity");
  Get get = new Get(Bytes.toBytes("userid1"));
        get.addFamily(Bytes.toBytes("pageviews"));
        get.setTimeRange(0,Long.MAXVALUE);
        Result result = table.get(get);
        byte[] value = result.getValue(Bytes.toBytes("pageviews"),
Bytes.toBytes("uri"));

        System.out.println(Bytes.toString(value));*

  This is fetching me only the column value with the latest timestamp.

I tried the same with Scan API. But I get the same result.

*Could you please let me know how I can retrieve all column values of all
timestamps of a particular rowkey??*

Many Thanks,
Narayanan
