Hello, I am trying to use Hadoop 3.1.1 on my cluster. I wish to experiment with the Hitchhiker Code which I believe was introduced in Hadoop 3 itself. I don't understand how do I activate the hitchhiker feature for the blocks of files I put on the datanode. I also don't know which erasure coding policy is being used by default on the uploaded blocks of files when I don't do anything. Any help regarding setting the erasure coding policy (and hitchhiker feature) would be appreciated.
It's a bit urgent. Warm regards, Shuubham Ojha
