Dedicated data and ingest node

I have to defined a dedicated data and ingest node, I set node.master to false, do I have to set node.data and node.ingest to true since this is the default ?

Note : I looked quickly on the forum and did not see an answer to my point.

No you don't have to.

Hi dadoonet,

Thanks for your answer.
(maybe the answer of exercise 3 of lab 5 of Engineering II could be improve )
