gridgain - Is there a configurable failure mechanism that can throw an exception if nodes go down from grid?

Question

Gridgain has failover spi mechanism for failure of jobs on nodes. However, we would like to configure a failure mechanism that throws exception even when once of the configured data nodes goes down.

How can we do this?

Answer 1

如果正在执行作业的节点出现故障，您是否试图阻止任务的故障转移并引发异常？（我不确定我是否理解正确，所以如果我错了，请纠正我）

如果我是对的，最简单的方法是配置NeverFailoverSpi，如下所示：

<bean id="ignite.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
    ...
    <property name="failoverSpi">
        <bean class="org.apache.ignite.spi.failover.never.NeverFailoverSpi"/>
    </property>
</bean>

另一种选择是使用IgniteCompute.withAsyncNoFailover()方法。如果您想为一小部分任务禁用故障转移，但仍对其他任务使用默认机制，这很有用。这是一个例子：

IgniteCompute compute = ignite.compute().withAsyncNoFailover();

// Tasks executed with this compute instance will never failover.
compute.execute(MyTask1.class, "arg");
