I've downloaded Apache Apex 3.5.0 along with Malhar 3.5.0.

I've successfully started the apex client and submitted the Yahoo Finance demo example to our YARN cluster (running CDH 5.10). The cluster is running and configured properly (many Spark and MR jobs are running on it).

I see the application I submitted as RUNNING in YARN as well as in the Apex cli. However when I try to connect to the Application Master I get a 404.

org.apache.hadoop.yarn.webapp.WebAppException: /: controller for default not found

I also tried directly to connect to the appMasterTrackingUrl reported by get-app-info command, and I get the same error.

I tried a couple of apex examples, and I always get the same error.

Any idea why?

有点意料之中。在 URL 路径中添加“/ws/v2/stram/info”

当您连接到 App Master 时，您需要提供完整的 URL 以供 REST API 调用。“/”没有什么可显示/返回的，所以你所看到的是预期的。你想做什么连接到App Master？
