gossip generation使用了int型承载数据，对应的是UTC时间的秒数，假如UTC秒到了整型的最大值，也就是2147483647秒(2038年某一时间)，下一秒后整型溢出，整个系统不会出问题么？

You've raised a good point. The gossip generation is used for internal tasks and in the event of an overflow, a node's gossip generation can be considered invalid so it may not be able to gossip with other nodes.
I would recommend logging a ticket with the Cassandra project so it can be addressed as a bug. Cheers!
