Any lessons from hbase deployments on on-premise products ?

[Venkat <rk...@gmail.com>]

All,

Are there users here who have deployed hbase on a production product
cluster that sits on customer premise ?  Any lessons learnt on
support/maintainability of such installations are greatly appreciated.

Apologize if this questions has been asked before and if this is the wrong
mailing list.

Thanks,
-Venkat.

Yes.

Every client is different. YMMV. 

You need to lock down certain functions, and you need to lock down certain tunable parameters. 
HBase isn’t a fire and forget type of system.

There’s not a lot that I can say. Sorry. NDAs can be a bitch. 
Overall, I’d say that HBase can be powerful, but at the same time fragile. 

If you have a customer who has their own dev staff … you need to be really careful. 
If its drop in and run w no additional development or monkeying with the cluster? Its going to be more stable. 
Also when you tune the cluster… don’t fine tune it, but leave some headroom…

Hi,

Our SPM <http://sematext.com/spm/> product (monitors HBase, Hadoop and a
bunch of other stuff) comes in On Premise version in addition to the Cloud
one, and it uses HBase to store all the performance metrics.   I can tell
you that the bulk of the Installation Guide is really about HBase (and thus
all the Hadoop pieces and ZooKeeper one has to set up).  While everything
ships in a VM and no separate installation of HBase & friends is needed,
it's still not super simple to set up or operate unless one either has
HBase people on the team or simply trusts that Sematext did a good job of
packaging, configuring, etc.  I think this is where some of the simpler
(from operational perspective) NoSQL DBs win. :(
