- Method Detail
  - getTaskSession
```
ComputeTaskSession getTaskSession()
```
    Gets current task session.
    
    Returns:
    
    Grid task session.
  - getJobResult
```
ComputeJobResult getJobResult()
```
    Gets failed result of job execution.
    
    Returns:
    
    Result of a failed job.
  - getBalancedNode
```
ClusterNode getBalancedNode(List<ClusterNode> top)
                     throws IgniteException
```
    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.
    
    Parameters:
    
    top - Topology to pick balanced node from.
    
    Returns:
    
    The next balanced node.
    
    Throws:
    
    IgniteException - If anything failed.
  - partition
```
int partition()
```
    Gets partition for IgniteCompute.affinityRun(Collection, int, IgniteRunnable) and IgniteCompute.affinityCall(Collection, int, IgniteCallable).
    
    Returns:
    
    Partition number.
  - affinityCacheName
```
@Nullable
@Nullable String affinityCacheName()
```
    Returns affinity cache name IgniteCompute.affinityRun(String, Object, IgniteRunnable) and IgniteCompute.affinityCall(String, Object, IgniteCallable).
    
    Returns:
    
    Cache name.
