Nikola Arnaudov commented on IGNITE-11837:
------------------------------------------
Hi Pavel,
Thanks for updating the JavaDoc.
What is the point specifying many hosts in client configuration as if the
client hit stopped node it will fail? Isn't there to mechanism to try another
host if one is down?
Greetings Nikola
