Hi Praba,
Thanks for your grate article and video... its very helpful for the installation
I too got the same error "Unsupported major.minor version 51.0" while eclipse plugin implementation. i am using java 6.1 (41) is this causing this error ? Any suggestion ?
I have a question regarding the replication of the system.
The replication is set to default which is 3. As I started uploading a file with 4 nodes in the cluster, only 3 nodes where given the replication. Why is that? And shouldn't the replication of the chunks be skipping?

Help plz

Hi Praba, thanks for sharing such and informative guide. I would also like to share my views-
With HDP for Windows and HDInsight Service there is unprecedented choice for Windows enterprises for their Hadoop deployments. HDP for Windows is the Microsoft recommended way to deploy Hadoop on Windows Server environments. For cloud-based deployments HDInsight Service is a 100% compatible and scalable environment for deploying your Hadoop based applications.
Would also like to suggest the newbies they can visit here also for more information-https://intellipaat.com/
Dear Prabha while i am installation of hadoop it is displaying
c:\hadoop-2.3.0\bin>hadoop namenode -format
The system cannot find the path specified.
Error: JAVA_HOME is incorrectly set.
Please update C:\hadoop-2.3.0\conf\hadoop-env.cmd
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.
The system cannot find the path specified.
Error: JAVA_HOME is incorrectly set.
Please update C:\hadoop-2.3.0\conf\hadoop-env.cmd
'-Djava.net.preferIPv4Stack' is not recognized as an internal or external command,
operable program or batch file.
I have done every thing what you said above and JAVA path also correctly set.
Please help in this regard.

Are you using windows xp 64 bit version , jdk 6 64 bit
because i built it for x64 only.......
if you using x64
follow this
1. Download the Yarn.cmd and replace C:\Hadoop-2.3.0\bin\yarn.cmd
https://raw.githubusercontent.com/prabaprakash/Hadoop-2.3-Config/master/bin/yarn.cmd[^]
or else
2. Open C:\Hadoop-2.3.0\bin\yarn.cmd in Notepad++
in the menu bar
" edit ->eol conversion -> windows format "
ctrl+s
I am using 32 bit as my machine is 32 bit.. I was able to build for 32 bit from hadoop source code by doing some settings changed in native code (two folders of native code in hadoop source, the original downloaded source code of hadoop is based on 64 bit).. Please help further on this. Thanks for your kind help.
