it's fine two place 2 replica on the local rack's nodes first and then the
third replica on the different rack node if the replica count is 3.
now consider the scenario for the replication factor 2. if it place these
two replica on the same rack, then you can loose all of your replica when
the
in some case you may not find the third node to place replica.

See HDFS documents, It says For the common case, when the replication
factor is three, HDFS’s placement policy is to put one replica on one node
in the local rack, another on a node in a different (remote) rack, and the
last on a different node in the same remote rack.
