windows - Zookeeper 节点在系统重启后被删除

Question

我正在尝试通过groovy在zookeeper中创建一个新节点，但是在系统重新启动后该节点消失了，就像它从未创建过一样。

此代码是 Jenkins 管道的一部分，它在针对某些 Windows VM 的后期构建 groovy 脚本中。然后管道然后在这台机器上执行重新启动并且节点消失。

我已经在其他几个 Windows 虚拟机上发生了这种情况

这是我的代码：

@Grab('org.apache.zookeeper:zookeeper:3.4.6')

import org.apache.zookeeper.*
import static org.apache.zookeeper.ZooKeeper.States.*
import org.apache.zookeeper.ZooDefs.Ids;

final int TIMEOUT_MSEC = 5000
final int RETRY_MSEC = 100
def num_retries enter code here= 0
PATH_TO_NODE = "/some/path/to/node"

noOpWatcher = { event -> } as Watcher

zk = new ZooKeeper('myIP', TIMEOUT_MSEC, noOpWatcher)


def addNode() {
    if (zk.exists(PATH_TO_NODE, true) == null) {
        /*create node*/
        println("creating nodes")
        zk.create(PATH_TO_NODE, new byte[0], Ids.OPEN_ACL_UNSAFE,
                CreateMode.PERSISTENT)

        zk.create(PATH_TO_NODE + "myNode", "someData".getBytes(), Ids.OPEN_ACL_UNSAFE,
                CreateMode.PERSISTENT)
    } else {
        println("node already exists")
    }

}

while (zk.state != CONNECTED && num_retries < (TIMEOUT_MSEC / RETRY_MSEC)) {
    Thread.sleep(RETRY_MSEC)
    num_retries++
}
if (zk.state != CONNECTED) {
    println("could not connect to zookeeper")
    System.exit(1)
} else {
    addNode()
}

zk.close()
