Deprecated Enum Constants

Enum Constant and Description
org.apache.hadoop.yarn.api.records.AMCommand.AM_RESYNC Sent by Resource Manager when it is out of sync with the AM and wants the AM get back in sync. Note: Instead of sending this command, ApplicationMasterNotRegisteredException will be thrown when ApplicationMaster is out of sync with ResourceManager and ApplicationMaster is expected to re-register with RM by calling ApplicationMasterProtocol.registerApplicationMaster(RegisterApplicationMasterRequest)
org.apache.hadoop.yarn.api.records.AMCommand.AM_SHUTDOWN Sent by Resource Manager when it wants the AM to shutdown. Note: This command was earlier sent by ResourceManager to instruct AM to shutdown if RM had restarted. Now ApplicationAttemptNotFoundException will be thrown in case that RM has restarted and AM is supposed to handle this exception by shutting down itself.
