I changed to port to 9000. As a result the hadoop server could not be
reached any more, according to the log.
Furthermore, using my original port hbase created a directory
structure under the dir I specify (attached)
On the hadoop namenode nothing is listening on 9000 (netstat -an |
grep 9000 comes back empty.)
Seems like the problem is somewhere else.
Thx - Arno

Arno,
The hbase.rootdir should look something like this for you :hdfs://
yowb0i0.mydomain.com:9000/tmparno/<http://yowb0i0.mydomain.com:8020/tmparno/
>
From what I see in your logs it is able to contact the Namenode but
unable
to retrieve the file, I think this is because you are using the
wrong port.

The quick response is much appreciated, thank you Jean-Daniel.
After configuring debug I deleted the old logs, configured a new
hbase
directory (to be clean) and started in distributed mode.
The the attached tarball contains configuration files, log files,
and a
screen trace.
There is an error in the region server log files about a possible
data
loss, but the reason seems not evident.
I think the debug mode resulted in the shell showing some internal
tables
upon the list command, still the error appears.
Thank you

Arno,
Could you enable DEBUG and see what it tells you? See
http://wiki.apache.org/hadoop/Hbase/FAQ#5
Also, I may recognize this trace and this NPE is thrown after all
the
retries were done to get a single row but for a dumb reason, we do
not
check
if something is null. (Even if it's not that, I'm going to open a
bug in
jira right away since I've already seen that)
What it would hide under this is that it cannot contact your region
server.
Maybe something is wrong with your configuration, please have a
look at
the
logs and look for anything exception.
Thx,

Hello
fresh install of hbase 0.18.1 & hadoop 0.18.2
hbase in non distributed mode w/o hadoop works fine
as soon as I add the configuration:
<property>
<name>hbase.rootdir</name>
<value>hdfs://yowb0i0.mydomain.com:8020/tmparno/</value>
<description>The directory shared by region servers.
</description>
</property>
and run bin/hbase shell
list
I get an error stack. However the hbase directory does get
created on
hdfs.
The attached error stack.
Thank you,
