What is the block placement policy hadoop follows when rack aware is not
enabled?
Does it just round robin?
Thanks.
It’s still random.
If rack aware is not enabled, all nodes are in “default-rack”, and random nodes
are chosen for block replications.

It appears to be randomly chosen. I just came across this blog post from
