                               @Nullable AffinityTopologyVersion topVer)

Initializes failover context.

Parameters:

taskSes - Grid task session.

jobRes - Failed job result.

loadMgr - Load manager.

partId - Partition.

affCacheName - Affinity cache name.

topVer - Affinity topology version.

Method Detail

getTaskSession

public ComputeTaskSession getTaskSession()

Gets current task session.

Specified by:

getTaskSession in interface FailoverContext

Returns:

Grid task session.

getJobResult

public ComputeJobResult getJobResult()

Gets failed result of job execution.

Specified by:

getJobResult in interface FailoverContext

Returns:

Result of a failed job.

getBalancedNode

public ClusterNode getBalancedNode(List<ClusterNode> top)

Gets the next balanced node for failed job. Internally this method will delegate to load balancing SPI (see LoadBalancingSpi to determine the optimal node for execution.

Specified by:

getBalancedNode in interface FailoverContext

Parameters:

top - Topology to pick balanced node from.

Returns:

The next balanced node.

affinityCacheName

@Nullable
public @Nullable String affinityCacheName()

Returns affinity cache name IgniteCompute.affinityRun(String, Object, IgniteRunnable) and IgniteCompute.affinityCall(String, Object, IgniteCallable).

Specified by:

affinityCacheName in interface FailoverContext

Returns:

Cache name.

partition

public int partition()

Gets partition for IgniteCompute.affinityRun(Collection, int, IgniteRunnable) and IgniteCompute.affinityCall(Collection, int, IgniteCallable).

Specified by:

partition in interface FailoverContext

Returns:

Partition number.

affinityTopologyVersion

@Nullable
public @Nullable AffinityTopologyVersion affinityTopologyVersion()

Returns:

Affinity topology version.

toString

public String toString()

Overrides:

toString in class Object
