Hmmm... sounds odd. Given the same memcached servers (config), the
hashing should be consistent.
FYI, all code for the experiments described in that tech report is in
cloud9, the library I use for teaching my courses. Download at:

Can you share some performance figures for typical workloads with your
HDFS/Fuse setup? Obviously, latency is going to be bad but throughput
will probably be reasonable... but I'm curious to hear about concrete
latency/throughput numbers. And, of course, I'm interested in these
Hi Stuart,
You might want to look at a memcached solution some students and I
worked out for exactly this problem. It's written up in:
Jimmy Lin, Anand Bahety, Shravya Konda, and Samantha Mahindrakar.

the Hadoop

Hi everyone,
I'm wondering if it's possible to lazily deserialize a Writable. That is,
when my custom Writable is handed a DataInput from readFields, can I
simply hang on to the reference and read from it later? This would be
useful if the Writable is a complex data structure that may be
the serialized version off the wire completely by
prepending the size. Then, we can read in the raw bytes and hang on
to them for later as we see fit. I would think that leaving the bytes
on the DataInput would break things in a very impressive way.

Hi Stephen et al.,
I would take advantage of the Hadoop plug-in for Eclipse to handle the
mundane aspects of putting together your job and running it on the cluster.
With respect to gentler introductions on application development, you
might want to take a look at the following:
Hi guys,
I was wondering if someone could explain the possible interaction
effects between the different methods available to control key sorting.
Based on my understanding, there are three separate knobs:
- a WritableComparable's compareTo method
- registering a WritableComparator
