Hadoop 2.6.0 Installation on Windows 7 for 32 bit

[Vinodh Nagaraj]

Hi All,

I am new bee to Hadoop and Java.

I tried to install ( D:\Hadoop_TEST\Hadoop\hadoop-2.6.0 ) Hadoop 2.6.0 on Windows 7 ( 32 bit ) for a single node cluster.

I followed this link http://www.srccodes.com/p/article/38/build-install-configure-run-apache-hadoop-2.2.0-microsoft-windows-os

I installed  Java 1.7.0.79 ( D:\Hadoop_TEST\jdk1.7.0_95 ).

Cygwin is installed on D:\Hadoop_TEST\cygwin.

Maven is installed on D:\Hadoop_TEST\maven\apache-maven-3.3.3\apache-maven.

Protocol Buffer is installed on D:\Hadoop_TEST\protobuf.

Installed Ms SDK version also.

Environment Variable.

CLASSPATH=D:\Hadoop_TEST\Hadoop\hadoop-2.6.0\share\hadoop\hdfs\hadoop-hdfs-2.6.0.jar

---------------------------

I can compile and execute java class files with out error,when i invoke  **hadoop version or hdfs version**,

I got the below error.

D:\Hadoop_TEST\Hadoop\hadoop-2.6.0\bin>hdfs -version

Error: Could not find or load main class org.apache.hadoop.util.PlatformName

java version "1.7.0_95"

Java(TM) SE Runtime Environment (build 1.7.0_95-b14)

Java HotSpot(TM) Client VM (build 24.95-b01, mixed mode)

D:\Hadoop_TEST\Hadoop\hadoop-2.6.0\bin>hdfs version

Error: Could not find or load main class org.apache.hadoop.util.PlatformName

Error: Could not find or load main class version

when execute hdfs namenode -format,i got the same error.

D:\Hadoop_TEST\Hadoop\hadoop-2.6.0\bin>hdfs namenode -format

Error: Could not find or load main class org.apache.hadoop.util.PlatformName

Error: Could not find or load main class org.apache.hadoop.hdfs.server.namenode.

I tried to change from set JAVA_HOME=%JAVA_HOME% to set JAVA_HOME=D:\Hadoop_TEST\jdk1.7.0_95 and added set HADOOP_PREFIX=D:\Hadoop_TEST\Hadoop\hadoop-2.6.0 in hadoop-env.cmd file. But NO USE.I got the same error.

I haven't added any changes in the files Yarn-site.xml,core-site.xml & hdfs-site.xml.

I checked this link <http://stackoverflow.com/questions/19680615/error-could-not-find-or-load-main-class-when-starting-hadoop>

Which says that "Note: You can install Hadoop2.2+ directly on Windows. You don't need Cygwin."

Should i install/Require CYGWIN ,MAVEN,PROTOCOL BUFFER and MS SDK for HADOOP 2.6.0?Lot Of  CONFUSIN.....

Same link says that "Add the following to ~/.bashrc file:

export HADOOP_CLASSPATH=$(cygpath -pw $(hadoop classpath)):$HADOOP_CLASSPATH "

I added "set HADOOP_CLASSPATH=%(cygpath -pw %(hadoop classpath))"

I got the below error  when execute hdfs version

D:\Hadoop_TEST\Hadoop\hadoop-2.6.0\bin>hdfs version

D:\Hadoop_TEST\Hadoop\hadoop-2.6.0\contrib\capacity-scheduler\*.jar was unexpected at this time.

 

I checked many links in net.But no use.

Please help me.

Thanks,
