Philipp,
For HBase-related questions, please post to hbase-user@hadoop.apache.org
Try importing commons-cli-2.0-SNAPSHOT.jar as well as any other jar in the
lib folder just to be sure you won't get any other missing class def error.

Bill,
So out of the box, with a straight-forward schema, you can store the data in
the way you want and have the efficient query of "get all key/vals for this
identifier".
In order to also implement "get all identifiers which have key X = value Y"
queries, you'd need to store your data in the inv

It's hard to say whether hbase is a good fit without knowing a bit more.
HBase is very well suited for storing data in the format you describe. If
your primary problem is scaling the persistence of this dataset, it can
certainly do that. You can have any number of a

I am afraid my question not clear.
I agree that we can backup database
just by scanning it and writing the data somewhere
while the database is running.
However, if we want to backup the database

Hi Michael!
I don't think that it is true that you can only backup system that are down,

What that will do for you is to scan the tables and serialize those to disk
and the
other way around when importing.
Hi, all
As I understand from the discussions on the list,
we can backup the file system only if Hbase is down.
If we want to run backup when Hbase is up
we can work on the Hbase level, i.e. use scan,
MR export/import utils, etc. but we cannot backup
on the file system level.
Is it correct?
