Hadoop Installation on Windows 7 in 64 bit

Vinodh Nagaraj
Hi All,

I tried to install Hadoop hadoop-2.7.2 on Windows 7 in 64 bit machine.
Java version 1.8.set path variables. It works fine.

Trying to execute start-all.cmd.got. Got the below error. I couldn't find folder conf in hadoop home.

U:\Desktop\hadoop-2.7.2\sbin>start-all.cmd
This script is Deprecated. Instead use start-dfs.cmd and start-yarn.cmd
Error: JAVA_HOME is incorrectly set.
       Please update U:\Desktop\hadoop-2.7.2\conf\hadoop-env.cmd


Any Suggestions.


Thanks,
Vinodh.N

Could you check %HADOOP_HOME%/etc/hadoop/hadoop-env.cmd path. May be, U:/Desktop/hadoop-2.7.2/etc/hadoop/hadoop-env.cmd location.

Typically HADOOP_CONF_DIR will be set to %HADOOP_HOME%/etc/hadoop. Could you check "HADOOP_CONF_DIR" env variable value, location of the hadoop cluster configuration.

Regards,
Rakesh

Hi Vinodh,

 

Are there any spaces in your JAVA_HOME path? If so you need to use the short (8.3) path. E.g. c:\progra~1\java (assuming you haven’t done so already).
