bq. all regions of that customer
Since the rowkey starts with , any single customer would only
span few regions (normally 1 region), right ?

Hi tom ,
Isn't the Bucket we use the same thing?
So if I understand correctly you are not using automatic splitting, but do
this throughout a manual process or a process running along HBase?
Regarding recommendation of merge of empty regions - how did merge regions?
I thought this capability exists
But when you read, you have to approach all regions of that customer,
instead of pinpointing just one which contains that hour you want for
example.

We have solved this by prefixing each key with a single byte. The byte is
based on a very simple 8-bit hash of the record. If you know exactly which
row you are looking for you can rehash your row to create the true key.
Scans are a little more complex because you have to issue 256 scans instead

bq. you must have your customerId, timestamp in the rowkey since you query
on it
Have you looked at this API in Scan ?
public Scan setTimeRange(long minStamp, long maxStamp)
Cheers

The problem is that I do know my rowkey design, and it follows people's
best practice, but generates a really bad use case which I can't seem to
know how to solve yet.
The rowkey as I said earlier is:
So when ,for example, you have 1000 customer, and bucket ranges from 1 to
16, you eventually end

You misspelled hbase.zookeeper.quorum (dot at the end)
config.set("hbase.zookeeper.quorum.", "10.219.47.22");

Hi I am trying to connect to hbase in a remote machine from my java program.
But I am getting connection refused error. On looking at the error I think
it is trying to connect to my localhost instead of the remote machine.
My configuration is like-
Configuration config = HBaseConfiguration.create
That code can be traced down to:
public static String[] getHosts(String strInterface, String nameserver)
throws UnknownHostException {
String[] ips = getIPs(strInterface);
Vector hosts = new Vector();
for (int ctr = 0; ctr < ips.length; ctr++)
try {
hosts.add(reverseD
Hum. I don't know why I was not able to find it before. Sorry about that.
Have you tried to directly call reverseDns from a small java class on your
server to see what is returned?

Asaf:
What doesn't work is that the RegionServers bind to the IP that the hostname
maps to in /etc/hosts and not to the specified interface.
I've this in hbase-site.xml:
hbase.master.dns.interface
eth0
hbase.regionserver.dns.interface
eth0
This however has
Asaf, which HBase version are you using? Also, hae you tried without those
properties?
