Hey all,
Work on the HDFS-1073 branch has been progressing steadily, and I believe
we're coming close to the point where it can be merged. To briefly summarize
the status:
- NameNode and SecondaryNameNode are both fully working and have undergone
some stress/fault testing in addition to a over
Do other apache projects have a good localization framework for error messages?
I'd think there would be interest in starting this, although since we'd need to
add the framework, this would be an investment.

I'd be hesitant about this given our experience with the Chinese
version of the Hadoop documents. Picking the Chinese version of
hdfs_quota_admin_guide.xml, as an example, shows that it has not
actually been updated (beyond svn moves and copyright years) since its
original commit back on 12/10/08
You can get 12-24 TB in a server today, which means the loss of a server
generates a lot of traffic -which argues for 10 Gbe.
But
-big increase in switch cost, especially if you (CoI warning) go with
Cisco
-there have been problems with things like BIOS PXE and lights out
management
That's not a question I'm qualified to answer. I do know we're now buying an
Arista for a different cluster, but there's probably loads others out there.

Keeping the amount of disks per node low and the amount of nodes high
should keep the impact of dead nodes in control.
It keeps the impact of dead nodes in control but I don't think thats
long-term cost efficient. As prices of 10GbE go down, the keep the node
small arguement seems less fitting.
You have to consider the long-term reliability as well.
Losing an entire set of 10 or 12 disks at once makes the overall reliability
of a large cluster very suspect. This is because it becomes entirely too
likely that two additional drives will fail before the data on the off-line
node can be

Good point Todd.

No worries.
I read Todd's post as asking for elaboration ... sometimes knowing what
another similar system does helps in improving your own.

Ian,
Good point. Srivas was responding to Todd's question, but there might be
better fora as you suggest.
We have a good one for specific questions about MapR at

That doesn't, however, really provide a useful forum for questions like
Todd's which really spans both

Java has very good localization capabilities. However, it is a huge
