Question

我在SpringXD中有以下流定义：

stream create dataListener --definition "gemfire --regionName=data --useLocator=true --host=lithium --port=10334 | null" --deploy

但它给了我以下错误，并标记为'失败'：

    [error 2015/04/09 16:09:20.265 ART  <poolTimer-client-pool-2> tid=0x59] Unexpected error in pool task <com.gemstone.gemfire.cache.client.internal.LiveServerPinger$PingTask@5a422dfd>

        at java.lang.Thread.run(Thread.java:745)

之前发生了这种情况，我通过重新启动VM来修复它。但是，我想知道如何以适当的方式解决它。

任何提示，解决方法或指南都会很有用。另外，如果您需要更多信息，请告诉我。

我使用的是最新版本的Spring XD，1.1.1和Gemfire 7.0.2版。定位器与流部署位于同一节点中。我也在使用单节点拓扑。

谢谢！

您是否在定位器/服务器日志中看到任何消息？

我无法在此处重现您的问题，您是否也可以分享如何启动定位器？

例外，在使用Gemfire源和SpringXD时部署失败
