Subject RE: JAVA cannot execute binary file
Date Wed, 08 Jan 2014 04:44:31 GMT



I have had, at some point on earlier versions of hadoop:
Inside hadoop-env.sh where you set /usr/lib/jvm/jdk1.7.0/  Leave off the final slash. instead
it should be /usr/lib/jvm/jdk1.7.0 

Somewhere at some point it adds the /bin/java on itself.  So you are getting a double slash
/usr/lib/jvm/jdk1.7.0//bin/java 
Really strange, I don't recall ever seeing it mentioned anywhere that I've seen and depending
on the version of Hadoop used, it will keep everything from running until you find it. 
I also was getting some strange errors using jdk or any non Sun/Oracle java back then though
too.
This was 3-4 years ago on whatever Ubuntu was modern but it's my best guess.


I just looked and my current test setup of Hadoop 2.2.0 on Ubuntu 10.10 HAS the trailing slash,
with no problems.

Seems like that you have a wrong JAVA_HOME. You can check whether the directory exists, or
search around a little bit to find the right configuration with respect to your distribution.

This could be because you are trying to run the incorrect version of java for your platform

 What do you see when you do the following

  

ubuntu@---:~$ file `which java`

/home/ubuntu/GERMAN/WORKLOADS/java/jdk1.7.0_25/bin//java: ELF 64-bit LSB executable, x86-64,
