Howdy,
I have an HBase schema-design related question. The problem is fairly
simple - I am storing notifications in hbase, each of which has a status
(new, seen, and read). Here are the API's I need to provide:
- Get all notifications for a user
- Get all new notifications for a user
- Get the

Hi,
I wanted to setup Hadoop and Hbase in one remote server and Hbase client

Please let me know which mode should the Hadoop and Hbase be running in the

Previously I had Hadoop, Hbase and hbase client all
You need a distributed mode, with no server binding to localhost.

Mostly just means that your ZooKeeper's zoo.cfg, Hadoop's
core-site.xml/mapred-site.xml, and HBase's hbase-site.xml - must *not*
carry localhost (or anything that resolves to 127.0.0.1) in it
anywhere, but rather use a hostname that identifies it, and is
accessible by your client node.

Try starting it as a regular, non-root user. This is an issue with
0.20.205 scripts, perhaps fixed in more recent releases, but you do
not want to be running Hadoop as root anyway.

Hi,
I'm investigating the import/export functionality in HBase, there's a lot
of hits on searches but every page I hit seems to assume that I have hadoop
installed as well as HBase (including the book, the definitive guide). Is
it really necessary for me to have Hadoop installed in order to use
The import/export tools are mapreduce programs but you can also run
them off Hadoop's local mode (default, when not configured), not
needing Hadoop setup as a cluster. HBase ships a hadoop jar in its
distribution by default, which should suffice.

Thanks Matt for point out the problems that can happen, I will look into
it. And thanks Neil for sharing more details about your infrastructure, it
has been of great help.
I will run some tests with these instances and make my choice according to
our needs. Thank you all for the time dispensed. :)
Thanks for that, I'm now backing up.
The resulting file format isn't very helpful other than if the requirement
is to restore to the same or another machine. My real investigation is not
just to backup it's to back up, modify the tables ie add a column family,
add some more tables etc. and then

Not including HBASE-5225(before 0.90.6.rc0). I think no relationship with this.

HBASE-5225 was merged for different purpose. But this issue does not seem
to be because of HBASE-5225.
Because in HBASE-5225 we tried to fix the case where the seq id is missed.
Here it is not missed it is still there in lastSeqWritten without getting
flushed.
