Do you mean the three files such as, part-0? If so, you can set
the number of reduce tasks as 1.

In my Eclipse Europa it is showing the attribute

Starry,
In .ssh directory you have to create a file config (without
extension) on every node.
Suppose server1 is your master and server2, server3 is your slave.
On the master (server1), in the config file and add the following
lines:
Host server2
User user2
Host server3
User user3
On

I am running Hadoop Cluster on windows. I have 4 datnodes. 3

be surprised if replication really wasn't happening. Can you run
fsck
and pay attention to Under-replicated blocks and Mis-replicated
blocks?
In fact, can you just copy-paste the output of fsck?

Hi Alex
Hi
I am a new Hadoop user. I have a small cluster with 3
Datanodes. In hadoop-site.xml values of dfs.replication property is 2
but then also it is replicating data on 3 machines.
Please tell why is it happening?

factor of 3. There
have
been cases when clusters running with a replication of 2 discovered
new
bugs, because replication is so often set to 3. That said, if you can
do
it, it's probably advisable to run with a replication factor of 3
instead
of
2.

done yet:
1. Check if your other hosts can ssh to master.
2. Take a look at logs of other hosts.

I also couldn't succeed in running it in ganymede.
I use eclipse europa with v. 0.19.0. I would give it a try for 19.1, though.

I am using Hadoop - HBase 0.18 and my eclipse supports
hadoop-0.18.0-eclipse
Try this page for eclipse europa:

This is the fastest for me,
if it's too slow, you can download from here:
