Hi,
I was looking at PrefixFilter but going by the implementation - it looks we
scan every row until we hit the prefix instead of seeking to the row with
the required prefix.
I was wondering if there are more efficient alternatives which would do a
real seek rather than scanning all rows. Would

Not after but only before hitting the prefix - I will check the startRow
stuff - I could not find where the seek happens for that...

HI,
I just upgraded Hbase to 0.94.2-cdh4.2.1, r
I also enabled snapshot in hbase-site.xml file on all master + RS machines
to:
namehbase.snapshot.enabled/name
valuetrue/value
But when I go to hbase shell, I can not find snapshotting related commands.
eg.
hbase list_snapshots
NameError:
Hi Ameya,
Can you login into the hbase shell and user the version command to make
sure which version you are currently running?
Thanks,

Hey all,
We're wanting to add 10 additional nodes to our 20-node HBase cluster. Our
tables are pre-split into 800 regions, 40 regions to a machine. What will
happen when we add 10 new nodes to the cluster? Will the HBase load
balancer automatically re-distribute these regions to the new nodes?
Yes, the if the balancer is enabled (balance_switch true), hbase will
automatically balance the tables across the new pool of region servers. At
this point your locality will be shot for those regions that have moved, so
I recommend running major compactions. If your total number of regions is
That is what my experience is. When we add nodes, the regions get rebalanced
across the old and new nodes..
