perfSONAR User Q&A and Other Discussion

[Antoine Delvaux <>]

Hello Pete,

I think I've found the reason for this.  I suspect the 
perfsonar-centralmanagement bundle dependencies have installed 2 versions of 
openjdk: 8 and 9 and cassandra is trying to run with 9 and failing.

Can you try to either change the default java to be openjdk-8 or even 
completely remove openjdk-9 from your server and then try starting cassandra 
again?

This should be possible with something like `apt-get purge 
openjdk-9-jre-headless` or any other openjdk-9 package you would have 
installed at the moment.

If you confirm this is the problem, I'll make a new cassandra package 
available in our repo that would conflict with openjdk-9.

Thanks,

Antoine.
