Hadoop Fans,
Lately, we've been spending a lot of time on the East Coast, and one thing
is clear: Hadoop is everywhere.
Hadoop usage on the East Coast tends to be slightly different. There are
still web companies with armies of tech gurus, but there are also many
"regular" industries and enterpri

Thank you that did work.
So I can connect while logged into the hbase master, all that remains is to
achieve connection from a remote machine. I think I'll try running my java
program from the hbase master as opposed from a remote machine and see it
that works.

the decommissioning process in hadoop takes a little while I thank there the
balancing bandwidth has a lot to do with it.
but to stop region server you should be able to run
bin/hbase-daemon.sh stop regionserver
on the server you want to stop the hbase as long as it not the master then
you can d
You should just subscribe to the mailing list and directly write to it
http://hadoop.apache.org/hbase/mailing_lists.html#Users ;)
If you can get, it means it works. You could also check if any
datanode is registered with the web ui at port 50070
60020 is the region server, is there anything wrong

Thank you very much for your reply. I add "hbase-user@hadoop.apache.org" to
"send to" of this email, so I think it will be seen by emaillist.
I do find datanode's log file show that it does not work, but when i solve
the datanode problem, the hbase still does not work.
is hadoop dir, I run
i use
hadoop hadoop-0.19.1

60010 is the default port for the web ui
60030 is the default port for the region servers
If you tried "telnet localhost 6" and it failed, then that's
probably because you specified "hbase01:6" in your hbase-site so
it was binded on whichever interface it is (most probably not
localhost).
I tried
- http://192.168.25.49:60010 from the browser and it works
- 192.168.25.49 60010 and it connects.
-
hbase.master
192.168.25.49:60010
throws an error in the console (see below) but nothing in the
log files.

Yeah for some reason it wasn't there yesterday. Here is part of the log from
one of the datanodes/region servers that went down:

Well the IP I was talking about is 192.168.25.49 so try

When I connected via http, I used the same IP from the same client machine as
with telnet. This works from the browser: http://hbase1:60010 as does
http://hbase1:60030.
For now, I'm stumped.

If you aren't able to telnet, then this is a network issue. Can you
figure why you can't telnet? When you connected via http, did you use
the same IP address and was it from the same client machine? Did you
try setting hbase1.qn-niat.net:6 as your hbase.master?

No, I am not able to telnet either. However, when I try to connect via http
on port 60010, I see a web page that says, "Master:
hbase1.qn-niat.net:6", which looks to me like the master is up and
running correctly. Also, the log files appear not to contain any errors.

Hello,
I just needed to remove 8 machines from our 33 node cluster. (hadoop-0.19.1,
hbase-0.19.2)
The first 4 nodes I decommissioned in hadoop with the exclude-file and hbase
running. After 4 hours I gave up and stopped the machines by hand (they

I'm trying to find some up-to-date hardware advice for building a Hadoop
cluster. I've only been able to dig up the following links. Given Moore's

Andy,
It seems to be there is version mismatch. What Hadoop and HBase version
you are using?

Go to the hosts where you think you run DataNodes and check what is set
for "HADOOP_LOG_DIR" in
$HADOOP_HOME/conf/hadoop-env.sh
(It is "$HADOOP_HOME/logs" by default.)
If there is no log like
"$HADOOP_LOG_DIR/hadoop-user-datanode-hostname.log"
in that dir I'd assume you are not running D
Hi Norbert,

Xudong Du,
While I appreciate answering HBase questions, I prefer to do that on
the HBase users mailing list for everyone's benefit.
Your problem seems to be that the HDFS Namenode is running but you
don't have any datanode, so the file was created in the namespace but
you can't read it. Make sur
