【问题描述】：
当我尝试使用 yahoo streaming-benchmark 测试 STORM 时，我得到了这些错误。我尝试在 ZooKeeper“zoo.cfg”文件和 kafka“server.properties”中将端口更改为 2080 而不是默认端口 2181。我仍然得到同样的错误。任何帮助将非常感激。提前致谢。 :-)

我找到了第一个错误的答案
java.lang.RuntimeException: No port is available to launch an inprocess zookeeper.这是因为在我们开始测试 Storm 基准之前 ZooKeeper 已经在运行。所以我们首先需要停止 ZooKeeper，在终端上使用以下命令cd $zookeeper_dir-version/bin/然后./zkServer.sh stop -
第二个错误
Error: Could not find or load main class .home.eranga.Software.kafka-0.10.0.1.config.server.properties的原因是我使用的是kafka的源码版本。我应该使用的是 kafka 的二进制版本。 （哎呀：-P 傻我）所以解决方案是下载二进制版本并将路径变量设置为该版本。我希望这对其他人有帮助:-) -
也许将您的解决方案标记为答案？

希望这样做 :-) 干杯。
