POST
Offline roles of a service.
Currently the offline operation is only supported by HDFS.
For HDFS, the offline operation will put DataNodes into HDFS IN MAINTENANCE state which prevents unnecessary re-replication which could occur if decommissioned.
The timeout parameter is used to specify a timeout for offline. For HDFS, when the timeout expires, the DataNode will automatically transition out of HDFS IN MAINTENANCE state, back to HDFS IN SERVICE state.

| timeout | Offline timeout in seconds. Offlined roles will automatically transition from offline state to normal state after timeout. Specify as null to get the default timeout (4 hours). | query | |
