Hmm, just as a follow up, using this command:
get 'iptable', '192.168.0.1', {COLUMN => 'details:phone', TIMESTAMP =>
1218532708269, VERSIONS = 4}
If you do 'VERSIONS => 4' instead of 'VERSIONS = 4', does it work? (I
fixed the hirb help where our example looked like the above).
St.Ack
Returns "SyntaxError: (hbase):8: , unexpected tRCURLY" -- is there
something I'm doing wrong?

Thanks Jean, much obliged. I don't suppose you know if this will be changed
in the future, so you're not required to enter a column?
Cheers.

Chris,
API docs : http://hadoop.apache.org/hbase/docs/current/api/index.htmltaken
from http://hadoop.apache.org/hbase/docs/current/
For your command, for the moment you really need to specify columns if you
want versions.

Hi Jean,
I was running Hadoop 16.4 / HBase 0.1.3 on a single VMWare node
(Ubuntu).
However having upgraded to Hadoop 17.1 / HBase 0.2.0 on the same hw it
inserts all of the rows in < 2 seconds - problem solved!
Also, do you know where can I find the API docs for 0.2.0?
Finally I'm having trouble with the syntax in the new shell for
retrieving
the latest 5 versions of a row. Off the top of my head (I'm away from my
desk now) I'm using "get 'iptable', '192.168.1.1', VERSIONS = 5" but
this
doesn't seem to work (removing the versions part does).
Cheers,
Chris

Chris,
It really seems slow yes. What's your setup like? # of machines, how
the
soft is installed, which version of hadoop/hbase, etc?
Thx,

Hey all,
I'm trying to insert a large number of rows into my table (about
5000)
and it's proving very slow - ~2 seconds / row. The data's very
simple,
with IP addresses being used as the row key and a single
10-character
string as the data (under a single column family, "Details", and
column, "PhoneNo"). There's also a timestamp (long) representing
time
since the epoch.
Below's the program I'm running to insert:
Text text = new Text(rowKey);
long lockid = tbl.startUpdate(new Text(rowKey));
tbl.put(lockid, new Text("Details:PhoneNo"), new Text(data));
tbl.commit(lockid, timestamp);
If anyone can see anything wrong with that I'm doing, please let me
know!
Cheers.
