@Anoop : Here is my situation: I have 2 columnFamilies(cf1,cf2),5-50
qualifiers(they are variable),first I should check the value of qualifiers
in cf2,then if they equal to some values I'm going to get the values of cf1
by that rowkey.
@Amita: thank you.I will check that too.

On Thu, Feb
Hbase-5416 should help your use case.
Cf2 would be the essential column family.
This feature is available in 0.94.5
Cheers

What is the purpose of the getAttribute and setAttribute methods for
classes implementing OperationWithAttributes? I don't see much
documentation about them, haven't seen much discussion on this list about
them, and am wondering what people use them for. Or, are they mostly just
used internally?
Hi everyone,
I had a quick question. do I need to be running datanode on the server
that is running hbase master or datanode should be running only on
servers that are running as regionserver?
thanks,

Hello Kaven,
It's not all necessary to run HM on server running DN. Actually it's
not advisable to do so, as HM has high memory requirements and running
other daemons on the same machine may lead you to problems. The basic
cluster setup, which people normally use looks somewhat like this :
Just to add to Mohammad's advices, you should avoid to run ZK on the same
servers as you are running HBase.
Reason is, if you are running in long GCs, ZK might miss the heartbeats and
thinks servers are down. So safer to run same separately if you can.

While this general guideline of not requiring a DN on HM is correct, I
just wanted to point out that the HM is hardly high on memory
usage/requirements (as possibly stated below), as all it does is
maintain the cluster and not serve nor hold any client-useful data or
frequent requests.
On Sat,
The attributes are serialized along with the base operation request.
There's perhaps no immediate client-side usage of this, it is used by
the Mutation class to set a cluster ID in HBase's Replication context:
So in case of a stand alone set up, how come we are not experiencing those
issues?
Is it because of the limited data set that we are operating on?

Hi Harish,
HBase still run ZooKeeper even in standalone mode:
http://hbase.apache.org/book/standalone_dist.html
So you still can face same kind of issues. But since it's not using Hadoop,
there is more memory available for you HBase, which might reduce GCs
issues.
