HBASE on Hadoop

[praveenesh kumar <pr...@gmail.com>]

Hello everyone,

Thanks everyone for guiding me everytime. I am able to setup hadoop cluster
of 10 nodes.
Now comes HBASE..!!!

I am new to all this...
My problem is I have huge data to analyze.
so shall I go for single node Hbase installation on all nodes or go for
distributed Hbase installation.??

How distributed installation is different from single node installaion ??
Now suppose if I have distributed Hbase...
and If I design some table on my master node.. and then store data on it..
say around 100M. How the data is going to be distributed.. Will HBASE do it
automatically or we have to write codes for getting it distributed ??
Is there any good tutorial that tells us more about HBase and how to work on
it ???

Thanks,
Praveenesh

Setup a "distributed" HBase cluster.

On each node that runs TaskTracker and Datanode, also run a HBase
RegionServer.

On the node that runs JobTracker and Namenode, run the HBase Master.

There is a getting started guide here.

Check out the HBase user list for more.

Praveenesh,

I will recommend you to read the google Big Table paper(
http://labs.google.com/papers/bigtable.html) which is a foundation for the
hbase.
Terminology is little different though:

Mapping of terms(not exhaustive):
***********************************
Big Table             Hbase
***********************************
Master Server      HMaster
Tablet                  region
Tablet server        regionserver
 chubby                zookeeper (It is apache implementation of distributed
synchronization server)

Hbase stores data on hadoop dfs. hbase is a client of hdfs. Hence hadoop
will automatically distribute and replicate the data across your hadoop
cluster.
Hbase master and regionservers formats/transforms the data and relies on
hadoop for storage and retrieval.


Hbase cluster can run on a separate set of nodes or it can even share hadoop
nodes.

Once you have setup hdfs cluster, hbase cluster can be easily setup.

Thanks
Gaurav
