我正在使用IMap进行锁定,遵循如何解释:
https://groups.google.com/forum/#!topic/hazelcast/9YFGh3xwe8I
IMap<Object, Object> locks = hazelcastInstance.getMap("locks");
locks.lock(someStr);
try {
//do stuff
} finally {
locks.unlock(someStr);
}
偶尔,行
locks.locks(someStr)
导致错误
com.hazelcast.core.HazelcastException: java.lang.InterruptedException:
Call BasicInvocation{ serviceName='hz:impl:lockService',op=com.hazelcast.concurrent.lock.operations.LockOperation{

Production中的集群包含两个节点。
我无法在本地重现此问题 我读过类似的例外情况,它与应用程序服务器时钟时间有关,导致两个远远不同步,但对我来说情况并非如此。
任何人都可以解释为什么会这样吗? 似乎我对IMap的使用非常简单。
答案 0 :(得分:0)
通常InterruptedException表示正在执行locks.lock(someStr);
的线程从程序的其他某个线程中断。
例如,您可以使用Thread.interrupt(),Future.cancel(true)或ExecutorService.shutdownNow()中断另一个线程。
