If the datanode is dead, block replications will be re-replicated on other
datanodes automatically. So, after a while, when those blocks have been
re-replicated, you should be able to delete the data on the dead nodes and
restart it. Here, I am assuming your cluster have enough space on other
live nodes for the block replications.
