      Description

      In a big cluster, when namenode starts up, it takes a long time for namenode to process block reports from all datanodes. Because heartbeats processing get delayed, some datanodes are erroneously marked as dead, then later on they have to register again, thus wasting time.

      It would speed up starting time if the checking of dead nodes is disabled when namenode in safemode.
