Hi all,
We are using hbase-0.94.6.1 and at moment i'm evaluation Snapshots as
backup solution for moving data between clusters. I'm wondering if someone
have similar experience and what are pros and cons ? Also is Snapshot
future stable enough for this sort of operation ?
Thanks,
Samir
Hi,
I know that HBase supports secure RPC between its nodes (Master, Region
Server). I have couple of questions about it:
1. Does HBase supports secure RPC between Master and Slave replications?
2. Does enabling security in HBase entails using the latest hbase security
branch?
3. Suppose the
Does enabling security in HBase entails using the latest hbase security
branch?
Which branch are you using? Once you enable security the security feature
on that branch starts working.
3. Suppose the only requirement I have is securing the RPC in between
Master and Slave sites, do I must have
Hi,
Could you describe a bit more what do you need by a backup, what do you
expect by it and what is your data flow?
A snapshot at the moment can guarantee just row level consistency.
This means that if you have in-flight writes some can be present in the
snapshot some not.
so, The best type of

Principally I chose to use Amazon, because they are supposedly high
performance, and what more important is: HBase is already set up if I chose
it as an EMR Workflow. I wanted to save up the time setting up the cluster
manually on EC2 instances.
Are you saying I will reach higher performance when
There is no separate branch for security features, they are integrated in
0.92 and 0.94. We did partition the security sources into a separate Maven
module for 0.92 and 0.94, out of an abundance of caution during development
of security features. (Some versions of Hadoop, e.g. 0.20, don't have the
If security is a feature, why HBase are releasing two version each time.
For instance 0.94.7 and 0.94.7-security?
For the 0.94 versions you need to use the tar ball that has security in it.
In trunk it is not so. I should have been clear on it.
So Andy has sent the mail in more detail.
Incase
What I am saying is that by default, you get two mappers per node.
x4large can run HBase w more mapred slots, so you will want to tune the
defaults based on machine size. Not just mapred, but also HBase stuff too. You
need to do this on startup of EMR cluster though...

Hi all,
I am New to Hbase(Hadoop), and i am working on hbase with standalone

Can you tell us the exact release of 0.94 that you're using ?
Check master log to see if there was any clue. You can pastebin log snippet
for us to see.

What do you get when you enter the status command?
(status 'simple' or just status should be sufficient.)
Just because you can start the HBase Shell doesn't mean that the cluster is up
and running properly.

Thank you for the detailed answer.
Regarding my 1st question - RPC for replication between master and slave
region servers is secured the same as RPC between region servers in the
same clusters? Is there a mechanism for exchanging keys between the master
