Hi All,
I started using HBase for a while and i am working on some open source

Now I am trying to update it to the latest Hadoop and HBase versions and I

Hi Jean,
We have upgraded to branch-0.20-append working with hbase 0.20.6. But it
looks we are still meeting the same problem. And today I found we started to
get tons of these issue when a Hadoop balance started. I am wondering will

Hi,
Is it recommended to use blades and SAN for hadoop/hbase cluster nodes ? or
will it be more performant to use seperate server machines with dedicated
CPU/hard disks on each of them.
Could using SAN cause a bottleneck or degrade performance for hadoop
nodes(using the same SAN for all nodes).
Thanks for your help. We are implementing our own secondary index table to
get rid of the scan and replace those calls with Get.
One common trend that we are following , to ensure the frontend web
application is performant as per our expectation, is to always try and use
Gets' from the UI instead

Hey Guys,
Not sure if this functionality is available or not, if its not consider this a
feature request :).
The main summary is that rows can contain massive amounts of data, so we can
narrow
selection by family. However, if the family is large enough is there a way to
grab parts of

Don't forget that a Get is just a 1 row scan, they share the same code
path internally. The only difference of course is that a get just
returns that one row and therefore is fairly fast (unless your row is
huge, think hundreds of MBs).

Dear all,
I have sent quite a couple of questions about the issue we met these days
which was killing my team.
We were now using hbase 0.20.6 with hadoop branch-0.20-append.
The region server will get tons of logs as following:

Thank you Stack! I will try applying to my code base and see if it works.
Thanks again

The issue says that it was applied to the branch for 0.90.2.Thats
a misstatement. The patch was not applied. Will apply to the branch
now.
In general, Hadoop applications will perform much better with dedicated
local disks (don't use RAID for data drives, either).

You'd have to hack it up into the thrift server, shouldn't be so bad
but there's no such doc.

The error message in the datanode log is pretty obvious about the
