Hi guys, I spend my time to read too much about setting replication factor as well as block placement so far. But I still wonder how setrep command is working behind in the code.
I am looking for answer to following questions: What if you have one rack and increase and decrease replication factor, is it block distribution will be randomised or based on disk usage etc. (except or after rack-awareness issue) ? And what if I have 5 rack and replication factor 4 ? I am looking for corner case to understand completely. I would be really appreciated if you can answer my question and explain code side bit more too. Regards, Egemen
