ignite使用注意事项
1.
解决：需要激活集群 ./control.sh --activate
2
WARN NoopCheckpointSpi: Checkpoints are disabled (to enable configure any GridCheckpointSpi implementation)
WARN GridCollisionManager: Collision resolution is disabled (all jobs will be activated upon arrival).
解决：作业被提交到一个线程池然后随机地执行，如果要对作业执行顺序进行细粒度控制的话，需要启用CollisionSpi
3
WARN TcpCommunicationSpi: Message queue limit is set to 0 which may lead to potential OOMEs when running cache operations in FULL_ASYNC or PRIMARY_SYNC modes due to message queues growth on sender and receiver sides.

class org.apache.ignite.binary.BinaryInvalidTypeException: TestIgnite$1
每个闭包都是一个特定类的对象。当它要被发送时会序列化成二进制的形式，通过线路发送到一个远程节点然后在那里反序列化。该远程节点在类路径中应该有该闭包类，或者开启peerClassLoading以从发送端加载该类。
