This does not look related to Apache Hadoop. Perhaps you want to post
this to the lucene's user lists?

When I am trying to run lucene example from command line, I get the
following exception.
[root@localhost lucene-3.4.0]# echo $CLASSPATH
/root/lucene-3.4.0/lucene-core-3.4.0.jar:/root/lucene-3.4.0/contrib/demo/lucene-demo-3.4.0.jar:/usr/java/jdk1.6.0_26/lib

Your NameNode is listening on localhost. In HDFS, your regular client
needs to simply communicate with a NameNode address to do its
operations -- you do not need to explicitly connect to a particular
DataNode.
Also, maybe as you grow your cluster you want to switch out
fs.default.name from localho
If you are just trying to list the HDFS content then just use:
bin/hadoop fs -ls
See if that command get you what you're looking for.

Sorry, a detailed description:
I wanna know how many files a datanode can hold, so there is only one datanode
in my cluster.
When the datanode save 14million files, the cluster can't work, and the
datanode has used all of it's MEM(32G), the namenode's MEM is OK.

In my understanding, the max number of files stored in the HDFS should be /sizeof(inode struct). This max number of HDFS files should be no
smaller than max files a datanode can hold.
Please feel free to correct me because I'm just beginning learning hadoop.

hi everyone
I useing hadoop-0.20.203.0,one master and one slave.
I can see one live datanode at: http://localhost:50070/dfshealth.jsp

Hello Uma,
Thanks for your cordial and quick reply. It would be great if you explain
what you suggested to do. Right now we are running on following
configuration.
We are using hadoop on virtual box. when it is a single node then it works
fine for big dataset larger than the default block size. b
I'm interested in this too.

Apparently the Adobe SaaS guys are responsible for creating a project for
puppet-Hadoop stack deployments...

Yes, I know ;) You can grab and extend the metrics as you like. Here a

Is there a tool or a method to measure the throughput of the cluster at a
given time? It would be a great feature to add

When running a program which runs concurrent map-reduce jobs, I get a
ClassCastException if I use waitForCompletion. (Not with submit, but I do
need the threads to wait for the jobs to complete. Is there a way to do
that with submit?)

Hey Humayun,
To solve the too many fetch failures problem, you should configure host
mapping correctly.
Each tasktracker should be able to ping from each other.

This is the easiest guide to configure hadoop.

someone please help me to configure hadoop such as core-site.xml,

please provide some example. it is badly needed. because i run in a 2 node
cluster. when i run the wordcount example then it gives the result too
mutch fetch failure.
Most places throughout the hadoop framework instantiate instances of the keys
with ReflectionUtils.newInstance(keyClass, configuration)
I thought that means I can configure the keys before they read or write, but
apparently this is not so. The attached example
