Hadoop
Hello all,
First of all sorry if this question sounds stupid. I am a
beginner with Hadoop.
I am using Hadoop at windows so I have installed java in
following directory
C:\cygwin\home\HadoopAdmin\java
I have given the java home as Hadoop-env file of hadoop configuration as
export JAVA_HOME=/home/HadoopAdmin/java/jdk6
but still if I run following command
/home/ HadoopAdmin/hadoop18.3/bin/hadoop namenode -format
It gives error that
There is no file or directory
HadoopAdmin//java/jdk6
Please help me on this matter
Best Regards,
Harjeet Kumar

Hi Harjeet,
Once you modify the Hadoop-env.sh file, you need to run it also. Please
run it using sh conf/hadoop-env.sh once after you modify your changes.
Thanks!
Amol.

Hi YONG YONG CHENG,
First of all thanks for reply. I used the path told by you as JAVA_HOME
but still its showing same problem.
After this I wrote command in cygwin as
export JAVA_HOME=C:\\cygwin\\home\\HadoopAdmin\\java
then it started running. Same happened with other export commands in
the file
C:\cygwin\home\HadoopAdmin\hadoop-0.18.3\conf\hadoop-env.sh
That means cygwin is unable to read commands from hadoop-env.sh file.
Can you suggest some thing on this.
Best Regards,
Harjeet Kumar

Good Day,
Use this:
export JAVA_HOME=C:\\cygwin\\home\\HadoopAdmin\\java
This should work fine.

You should set JAVA_HOME like this:
export JAVA_HOME=C:/cygwin/home/HadoopAdmin/java
