在本地模式下运行的Twitter风暴示例无法删除文件

Question

我正在运行风暴启动项目(https://github.com/nathanmarz/storm-starter),并在运行一段时间后抛出以下错误.

23135 [main] ERROR org.apache.zookeeper.server.NIOServerCnxn  - Thread Thread[main,5,main] died 
java.io.IOException: Unable to delete file: C:\Users\[user directory]\AppData\Local\Temp\a0894222-6a8a-4f80-8655-3ad6a0c10021\version-2\log.1

我已经尝试更改"AppData"目录的权限,但这似乎不会影响它.这个错误会在命令行以及eclipse中运行.

根据Windows上的此文件删除问题,风暴版本0.8.2中仍存在此问题.截至目前,以下解决方案对我有用.您可能需要注释掉cluster.killTopology() and cluster.shutdown()方法,如下所示,以避免文件删除错误.

 LocalCluster cluster = new LocalCluster();
        cluster.submitTopology("test", conf, builder.createTopology());
        Utils.sleep(10000);
       // cluster.killTopology("test");
       // cluster.shutdown();  

希望这可以帮助
