OSError: [Errno 17] File exists

I'm keeping getting this error for one node on the Ambari installation wizard. Other nodes are fine and free of this error.

This is the node where Ambari-Server also operates. Maybe shouldn't select a ambari-server node as client?

I have totally no clue what's wrong with my cluster design and any help is greatly appreaciated!

@Yu Song

When are you getting this error ?

Is it while starting the ambari agent process ?

[#3]

@Sagar Shimpi

No, I'm getting this during the HDP service installation via Ambari wizard.

This error happens at any to-be-installed service on a certain node.

Using public repo. on Ubuntu 14.04 - 64bit.

Keep getting this error.

@Yu Song Is the host on which your are installing had /usr/hdp directory already present (before starting installation). What is the output of ls -l /usr/hdp/current

[#5]

@Yu Song

Can you list down the content of the /usr/hdp directory. If you find any other folder other than current and hdp version (like 2.2.9.xxxx) then remove or move that to /tmp and proceed with installation.

[#6]

@Yu Song: you can check which service is giving this error.

after that you need to remove the sym link of that service from /usr/hdp/current/ directory and restart the installation of that service.

[#7]

@Yu Song

If it is a fresh installation, remove the /usr/hdp folder for the node and then trigger the installation.

But better is run the clean up script and trigger the installation.

[#8]

Just to add, if any of the component is installed then package of that component will not reinstall, so in case any file of that component is removed from /usr/hdp directory, then start of the service for that particular component will fail.

Correct me if I'm wrong.
