NO.2 What action occurs automatically on a cluster when a DataNode is marked as dead?
A. The NameNode forces re-replication of all the blocks which were stored on the dead DataNode.
B. The next time a client submits job that requires blocks from the dead DataNode, the JobTracker
receives no heart beats from the DataNode. The JobTracker tells the NameNode that the DataNode
is dead, which triggers block re-replication on the cluster.
C. The replication factor of the files which had blocks stored on the dead DataNode is temporarily
reduced, until the dead DataNode is recovered and returned to the cluster.
D. The NameNode informs the client which write the blocks that are no longer available; the client
then re-writes the blocks to a different DataNode.
