| If remote job resulted in exception (<a href="../../../../../org/apache/ignite/compute/ComputeJobResult.html#getException--"><code>ComputeJobResult.getException()</code></a> is not <code>null</code>), |
| then <a href="../../../../../org/apache/ignite/compute/ComputeJobResultPolicy.html#FAILOVER"><code>ComputeJobResultPolicy.FAILOVER</code></a> policy will be returned if the exception is instance |
| of <a href="../../../../../org/apache/ignite/cluster/ClusterTopologyException.html" title="class in org.apache.ignite.cluster"><code>ClusterTopologyException</code></a> or <a href="../../../../../org/apache/ignite/compute/ComputeExecutionRejectedException.html" title="class in org.apache.ignite.compute"><code>ComputeExecutionRejectedException</code></a>, which means that |
| remote node either failed or job execution was rejected before it got a chance to start. In all |
| other cases the exception will be rethrown which will ultimately cause task to fail.</div> |
