Cannot install Spark IM 2.6.3, getting permission denied error even though I am root

  • 772

I am trying to install Spark IM in my Ubuntun VM, however I am running into all kinds of problems. The steps I have taken so far were:

  1. Download the tar.gz file from the website
  2. Unpack it
  3. cd /home/user/Downloads/Spark
  4. sudo chmod +x Spark
  5. sudo chmod +x starter
  6. cd ..
  7. sudo mv Spark/ /opt

To run, the Spark IM, I do the following commands:

  1. sudo su
  2. cd /opt
  3. sh Spark/Spark

And as a result, I get the error:

Preparing JRE ...
Spark/Spark: 150: Spark/Spark: bin/unpack200: Permission denied
Error unpacking jar files. Aborting.
You might need administrative priviledges for this operation.

Which makes no sense at all, because I am running in root mode. If I run sh Spark/starter I get the exact same mistake. If I try to run it as an executable file, I get a similar error:

bash: ./Spark/starter: Permission denied

What am I doing wrong? Why can I not install this?

    The reason you are getting permission denied is because the files Spark and starter don't have execute permissions as seen here: 

    -rw-rw-rw- 1 root root 8528 Jan 20 19:38 Spark
-rw-rw-rw- 1 root root 7520 Jan 20 19:38 starter

    So you will need to run: 

    sudo chmod +x /opt/Spark  
sudo chmod +x /opt/starter

    I'm not sure why the execute permission was lost (since you ran chmod +x before), but I think it is because when you moved them to /opt the owner was changed from you to root.
