hadoop setup

Hi ,

 

I am very new to Hadoop. I am trying to run few sample prog. In Standalone
(or local) mode. I have installed Cygwin in my windows machine. I am trying
to run the command "hadoop version" to verify whether hadoop installed
successfully or not. I have downloaded hadoop-2.2.0 version.

 

 

I have downloaded hadoop :  C:\Users\Pavan\Downloads\

 

I tried to setup the PATH variable in Cygwin as below

 

 

$ echo $JAVA_HOME

C:\Program Files\Java\jdk1.6.0_32

$ export HADOOP_INSTALL=/cygdrive/c/Users/Pavan/Downloads/hadoop

$ export PATH=$PATH:$HADOOP_INSTALL/bin:$HADOOP_INSTALL/sbin

 

I am trying to run the command "hadoop version" and end up with the
following error. Please help me in resolving this error.

 

$ hadoop version

java.lang.NoClassDefFoundError: org/apache/hadoop/util/VersionInfo

Caused by: java.lang.ClassNotFoundException:
org.apache.hadoop.util.VersionInfo

        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

Could not find the main class: org.apache.hadoop.util.VersionInfo.  Program

exit.

Thanks

As of the last release, Hadoop 2.2 supports Windows natively. Thus, old
workarounds like Cygwin are now un-supported. Please refer to the new
documentation mentioned below (and copied here) for latest instructions
for Hadoop on Windows.

https://wiki.apache.org/hadoop/Hadoop2OnWindows

If you are running Hadoop 1, then please check out branch-1-win and use
that for running Hadoop 1 natively on Windows.

Hi,

Everyone mentioned that using Cygwin we can try Hadoop on windows.

Ex:The book "Hadoop: the definitive guide by Tom white" also mentions
this.

Cygwin is not supported.

Please see https://wiki.apache.org/hadoop/Hadoop2OnWindows for Windows
installation.

Also JAVA_HOME should not have any spaces.
