/**
* This annotation allows to call a method right before job is submitted to
* {@link org.apache.ignite.spi.failover.FailoverSpi}. In this method job can re-create necessary state that was
* cleared, for example, in method with {@link ComputeJobAfterSend} annotation.
* <p>
* This annotation can be applied to methods of {@link ComputeJob} instances only. It is
* invoked on the caller node after remote execution has failed and before the
* job gets failed over to another node.
* <p>
* Example:
* <pre name="code" class="java">
* public class MyGridJob implements ComputeJob {
* ...
* @ComputeJobBeforeFailover
* public void onJobBeforeFailover() {
* ...
* }
* ...
* }
