Thanks Denis,
The version is 2.5 and we are indeed using persistence. Full config
attached.
Another weird thing that happened is that after restarting the node a few
time it starts properly and joins the cluster. However, when I try to
create a SQL table (from spark) using template "ga_template" (defined in
the config) I get the error *Cache doesn't exist. *After some time, with
the same code and settings, creating the table starts working.
I know it sounds odd, but I have observed both a few times.
Based on the link you sent, the node Id should be automatically picked up
from the name of the file in persistence directory. Is it possible that the
pst lock was not being released properly, so when the node was restarted it
tried to create a new UUID?
Cheers,
Eugene
