configure impala specialization with coordinators and executors

I would like to know how to calculate the number of coordinators and executors in the impala cluster?


today I have 23 nodes with only impala daemon, what would be the best division of coordinators for and executors for impala?

Hi @yagoaparecidoti ,


Each host that runs the Impala Daemon acts as both a coordinator and as an executor and if you want to deploy dedicated coordinators and executors please refer the below documentation for complete details:

Thank you for the link.


another question that popped up:


we didn't find anything saying if the coordinators can be used in virtual machines, can you tell us if there is a problem?
