I second Joeś comment.
Thanks for giving us a heads up.
I will wait patiently until 0.23 is considered stable.

API-wise, 0.21 is better. I know that as I'm working with 0.20.203 right
now, and it is a step backwards.
Regarding future releases, the best
Yeah... you can do that...
I haven't tried to mix/match different releases within a cluster, although I
suspect I could without any problems, but I don't want to risk it.
Until we have a problem, or until we expand our clouds with a batch of new
nodes, I like to follow the mantra... if it

Hello list,
sorry, sent this email to the wrong list, I think (MapReduce-list had
*no* activity the last whole day?).
As a newbie I got a tricky use-case in mind which I want to implement
with Hadoop to train my skillz. There is no real scenario behind that,
so I can extend or shrink the problem

Your SSH isn't setup properly
Setup passphraseless ssh
Now check that you can ssh to the localhost without a passphrase:
$ ssh localhost
If you cannot ssh to localhost without a passphrase, execute the
following commands:
$ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
$ cat ~/.ssh/id_dsa.pub
That is the strangest part, I never set it up as as root, this root just
came with the error. I have a dedicated hadoop user that I'm using, it
worked fine the first time and I tested it with the word count example which
produced the expected result but when I restarted the computers this error
I can ssh into locahost, even the hadoop user can ssh into localhost without
any error when I try starting hadoop it then that error comes.

Hi Shrinivas,
There has been some work going on recently around optimizing checksums. See
HDFS-2080 for example. This will help both the write and read code, though
we've focused more on read.
There have also been a lot of improvements around random read access - for
example HDFS-941 which

You can't run a hadoop job in eclipse, you have to set up an environment on
linux system. Maybe you can try to install it on WMware linux system and run
the job in pseudo-distributed system.
