bsridhar123 commented 7 years ago

Hi,

I am having some exceptions when using ZUUL with Websphere Liberty Profile.

The stacktrace I see for ZUUL logs is as below,

[utor-thread-104] o.s.c.n.z.filters.post.SendErrorFilter   : Error during filtering

Complete log with exception stacktrace for zuul is at, https://github.com/bsridhar123/spring-cloud-demos/blob/master/logs/zuul-logs.log

For all the participating services it is at,

https://github.com/bsridhar123/spring-cloud-demos/tree/master/logs

The complete codebase I used to reproduce the error is in https://github.com/bsridhar123/spring-cloud-demos

I do not see any exceptions when I ran the same with embedded tomcat.

But, I seem to see the issues only when running in WAS Liberty.

This seems similar to my earlier issue, #958

Can you please help me on this.

Thanks, Sridhar

ryanjbaxter commented 7 years ago

If I am understanding you correctly it looks like the request through Zuul is timing out. Notice the Hystrix timeout exceptions in the stacktrace. You might want to try increasing hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds.

bsridhar123 commented 7 years ago

@ryanjbaxter I tried increasing the timeout as follows in zuul application.properties,

hystrix.command.default.execution.isolation.strategy=THREAD
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=20000

I now see the below exception stacktrace in ZUUL logs, when accessing endpoint directly from ZUUL

@ryanjbaxter I even tried to disable timeouts as below,

hystrix.command.default.execution.timeout.enabled=false

But, I now see the connect exception in stacktrace as below in zuul logs,

ryanjbaxter commented 7 years ago

is demo-service making the request to Zuul or is it the service being proxied to by Zuul? It seems like the problem now is that Zuul cannot make a connection to the service, is PC249234.demo.com:2080 the correct address for the service?

bsridhar123 commented 7 years ago

I have tried both the ways, one when directly proxied by ZUUL and accessed via ZUUL proxy endpoint from a REST Client.

The other is consuming from demo-service-client via ZUUL proxy endpoint. The demo-service-client invokes the ZUUL proxy endpoint using RestTemplate..

I am seeing exceptions in both scenarios.

Yes. the demo-service service is running fine and is also accessible directly from its host and port.

All services including zuul/eureka/demo-service and demo-service-client are currently in the same host machine , although they run on different ports.

ryanjbaxter commented 7 years ago

So if I understand you correctly demo-service is the service being proxied to by Zuul and demo-service-client is calling demo-service via Zuul, correct?

Like I said above the problem appears to be that Zuul cannot connect to demo-service. For whatever reason Zuul cannot connect to PC249234.demo.com:2080. That problem is hard for me to debug.

bsridhar123 commented 7 years ago

Is there anyone who has found a similar issue when using ZUUL. If so, can you please provide me your suggestions on resolving it.

ryanjbaxter commented 7 years ago

Have you determined that the machine running your Zuul app can reach PC249234.demo.com:2080?

bsridhar123 commented 7 years ago

Let me summarize what I have found so far. Not sure if it makes sense.

By default Embedded tomcat exposes both localhost as well as "PC249234.demo.com" as the httpEndPoint, when started up.

Also, when registering with eureka service registry it is registered with "PC249234.demo.com"

But, with default configuration of liberty server, it only exposes "localhost" as httpEndpoint.

But, still when the service deployed to liberty server(on same port as liberty server ) it registers with eureka service registry, as "PC249234.demo.com"

So, whenever there is a forward from zuul to the downstream service it fails due to connect exception. Even tho' both zuul and downstream service are running in a same machine but on separate liberty servers and listening on different ports, we have this connect exception.

So, I had to change the configuration of liberty server to expose all network interfaces and not just the default host(localhost),which means both "localhost" and "PC249234.demo.com" can now be used as httpEndPoints. The below liberty server config with host attribute exposes all interfaces. Not sure if its optimal/safe to expose all interfaces like this.

<httpEndpoint host="*" httpPort="2080" httpsPort="9444" id="defaultHttpEndpoint"/>

But, still I am not sure how this works because as per my understanding, the default "localhost" should work from same machine and I had both zuul and downstream on same machine tho' on different ports and different servers. But, somehow it didn't work as expected.

Anyway, with this change I was able to access the downstream service running on standalone liberty server as either http://localhost:2080 (OR) http://PC249234.demo.com:2080

And so, ZUUL endpoint also works fine, because it is now able to connnect to the exposed , http://PC249234.demo.com:2080

I am not sure if this will always work or not. But, seems it does not have to anything with zuul/spring cloud netflix API . Its only due to the difference in exposing httpEndPoints for embedded Tomcat and liberty in standalone mode.

I hope the same thing works when I try to explore with spring boot and embedded liberty server next.

Let me know if this sounds correct or not.

Thanks, Sri

I agree that it wasn't an issue with spring cloud Netflix
