taskSes - Grid task session.

jobRes - Failed job result.

loadMgr - Load manager.

Method Detail

getTaskSession

public GridComputeTaskSession getTaskSession()

Specified by:

getTaskSession in interface GridFailoverContext

Returns:

Grid task session.

getJobResult

public GridComputeJobResult getJobResult()

Gets failed result of job execution.

Specified by:

getJobResult in interface GridFailoverContext

Returns:

Result of a failed job.

getBalancedNode

public GridNode getBalancedNode(List<GridNode> top)
                         throws GridException

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

Specified by:

getBalancedNode in interface GridFailoverContext

Parameters:

top - Topology to pick balanced node from.

Returns:

The next balanced node.

Throws:

GridException - If anything failed.
