Hi,
I've been trying to install AsterixDB with the above mentioned changes in a
cluster but I get the following error
WARNING!:Cluster Controller not running at node0
The cluster earlier had AsterixDB 0.86 installed. I haven't changed the
configurations of the cluster and I am using the same cluster configuration
file. Should I perform some manual cleanup before installing the later
version in a system which had 0.86 installed?
I have attached the cluster configuration file for reference.
Thanks,
Vignesh
