Thats a fine idea. Fill any notions you have of how this might work
into HBASE-50.
I imagine that this kind of question is among the least of your
concerns at this stage in hbase's evolution, though.

We're actually hoping to use Hbase in an online production capacity,
so I don't think we could shutdown regularly enough to protect the
data. We could probably stand to lose about 15 minutes worth of data,
but couldn't shut down more than once a day. Ideally we'd have some

Can you afford to shutdown hbase? Shutting down hbase will force it to
dump whats in-memory out to the Filesystem. Once its down, run a distcp
between your EC2 HDFS and S3? Would that work for you?
Otherwise, there is no mechanism of taking a snapshot of hbase currently
(HBASE-50 is about t
Does anyone have any experience with backing up data for an HBase
cluster on Amazon EC2 instances? We could take snapshots of the
filesystem on a regular basis and dump to S3, but I was wondering if
anyone had any other strategies to recommend? EC2 instances can
theoretically drop at anyt
Hi ,
Yes u can connect remotely to Hbase. For that
1. Hbase version on both machines.
2. Both machines should have similiar Hbase configuration .
3. HMaster should be running on node A for accepting connections from B.
Just try this out and also check the Hadoop logs directory for Hbase related
Thats great, but it won't do what he wants, as he want only rows where
the value for the status: column equals getBytes(1). Hence the
filter.

If you want to get all the family members, you can just specify
'familyname:' as the column. This creates a wild-card scanner
which will do what you want without filters.

I was having a similar problem as well. Though I've never used just
the column families to specify the columns (eg always fully qualified
col names like family:col) . Maybe you can try my patch and see if it
fixes your problem.

Hi
is there any posibility to connect to hbase from remote machine ?
i have two machines : A and B, and i have setup on A hadoop 0.17 with
newest hbase from svn.
but i cant connect from B to A:6. (all firewalls are disabled)
on netstat i see that connection to hbase is enable only f
Hi,
I am trying to obtain a set of rows by obtaining a scanner
on Htable. I also specify the RowFilterCriteria like this.
/* Code Start */
Map columnFilter = new HashMap();
columnFilter.put(new Text("status:"), getBytes(1));
RowFilterInterface rowFilter = new RegExpRowFilter(".*", columnFilte
