vCloud Director 9 can't connect to cassandra DB

[nutthanon]

Hi.

I just build new vcd 9 in my environment and it function work seem fine.

The problem is when I need vcd cell to send metric data to cassandra db for test matric in html5 but it can't as error below

So I check in cell manager tool log and it look like this.

Then I check on my cassandra db but everything seem fine, I can telnet to port 9042,9160 and run cqlsh on localhost or remotely from other cassandra node (firewalld disabled)

Are there any recommend for this case? I'm quite new for cassandra db,Thank you.

If you haven't configured SSL for your Cassandra cluster, you need to add the following to your vCloud Director global.properties file:

cassandra.use.ssl = 0

I know this caused issues for some people in the vCD 9 beta too.

It's worked.

This solved my issue.

Thank you

If this command:

opt/vmware/vcloud-director/bin/cell-management-tool cassandra -configure -create-schema -cluster-nodes xxxxxxxxxx -username root -password xxxxxxxx -port 9042 -ttl 15

Should I perform on every CELLs ? or only on one?

I'm asking because on the first CELL we had success:

and next when we tried to perform that same command on 2nd CELL we received errors:

OK i received sufficient answer on vExpert community slack from Tomas Fojta:

"All cells share the same Cassandra DB (keyspace), and the node list is store in vCloud DB. So you run the Cassandra configuration only from one cell."

Thanks
