How Hadoop distributes block writes into HDFS?

0 votes
My Hadoop cluster has the following configurations: 12 slave nodes, a block size set to 64MB, and a replication factor of three.
How the Hadoop Framework distributes block writes into HDFS from a Reducer outputting a 150MB file?

Can someone help please?

So, what happens is the slave node on which the Reducer runs gets the first copy of every block written. Other block replicas will be placed on other nodes.
