| [hadoop@hadoop-master1 ~]$ hdfs haadmin -transitionToActive --forcemanual nn1 | |
| You have specified the forcemanual flag. This flag is dangerous, as it can induce a split-brain scenario that WILL CORRUPT your HDFS namespace, possibly irrecoverably. | |
| It is recommended not to use this flag, but instead to shut down the cluster and disable automatic failover if you prefer to manually manage your HA state. | |
| You may abort safely by answering 'n' or hitting ^C now. | |
| Are you sure you want to continue? (Y or N) Y | |
