For 1#, since you still have 2 datanodes alive, and the replication is 2,
writing will success. (Read will success)
For 2#, now you only have 1 datanode, and the replication is 2, then initial
writing will success, but later sometime pipeline recovery will fail.

Hi Users,
I want behaviour for hadoop cluster for writing/reading in following
replication cases:
1. replication=2 and in cluster (3 datatnodes+namenode) one datanode gets down.
2. replication=2 and in cluster (3 datatnodes+namenode) 2 datanode gets down.
BR,
Satyam
