我一直在使用ide(eclipse)测试storm拓扑的远程提交。我成功地将简单的storm拓扑上传到远程storm集群,但奇怪的是,当我检查storm ui以确定远程提交的拓扑是否正常工作时,我在ui中只看到了\u acker bolt,但其他bolt和spout不在那里。之后,我从命令行手动提交了拓扑,并再次检查了StormUI,它可以正常工作,没有任何问题。我一直在找原因,但找不到。我在下面附上了拓扑和远程提交者类以及相应的storm ui图片:
这是eclipse控制台的输出(在远程提交之后)

这是storm ui图片(在远程提交的情况下)
这是另一个storm ui图片(在手动提交的情况下)

按热度按时间bnl4lu3b1#
在
RemoteSubmissionTopo
你用TopologyBuilder topoBuilder = new TopologyBuilder();
但不要打电话setSpout(...)
/setBolt(...)
. 因此,您提交的拓扑没有运算符。。。顺便说一句:
RemoteSubmissionTopo
实际上根本不需要。你可以用StormBenchmark
远程提交。只需添加conf.put(Config.NIMBUS_HOST, "117.16.142.49");
在main
并设置jvm选项-Dstorm.jar=/path/to/topology.jar
你很适合跑步。
