But if the backpresure/storm-id dir is not empty and has not been updated for more than timeoutMs, we treat it as throttle-off. This will prevent the spouts from getting stuck indefinitely if something wrong happens.- Specified by:
topologyBackpressurein interfaceIStormClusterState- Parameters:
stormId- The topology IdtimeoutMs- How long until the backpressure znode is invalid.callback- The callback function- Returns:
- True is backpresure/storm-id dir is not empty and at least one of the backpressure znodes has not timed out; false otherwise.

getPrivateWorkerKey
public PrivateWorkerKey getPrivateWorkerKey(WorkerTokenServiceType type, String topologyId, long keyVersion)
Description copied from interface:IStormClusterStateGet a private key used to validate a token is correct. This is expected to be called from a privileged daemon, and the ACLs should be set up to only allow nimbus and these privileged daemons access to these private keys.- Specified by:
getPrivateWorkerKeyin interfaceIStormClusterState- Parameters:
type- the type of service the key is for.topologyId- the topology id the key is for.keyVersion- the version of the key this is for.- Returns:
- the private key or null if it could not be found.
-
addPrivateWorkerKey
public void addPrivateWorkerKey(WorkerTokenServiceType type, String topologyId, long keyVersion, PrivateWorkerKey key)
Description copied from interface:IStormClusterStateStore a new version of a private key. This is expected to only ever be called from nimbus. All ACLs however need to be setup to allow the given services access to the stored information.- Specified by:
addPrivateWorkerKeyin interfaceIStormClusterState- Parameters:
type- the type of service this key is for.topologyId- the topology this key is forkeyVersion- the version of the key this is for.key- the key to store.
-

public long getNextPrivateWorkerKeyVersion(WorkerTokenServiceType type, String topologyId)
Description copied from interface:IStormClusterStateGet the next key version number that should be used for this topology id. This is expected to only ever be called from nimbus, but it is acceptable if the ACLs are setup so that it can work from a privileged daemon for the given service.- Specified by:
getNextPrivateWorkerKeyVersionin interfaceIStormClusterState- Parameters:
type- the type of service this is for.topologyId- the topology id this is for.- Returns:

This should be for all service types. This is expected to only ever be called from nimbus and some ACLs may be setup so being called from other daemons will cause it to fail.- Specified by:
removeExpiredPrivateWorkerKeysin interfaceIStormClusterState- Parameters:
topologyId- the id of the topology to scan.
-
removeAllPrivateWorkerKeys
