Hi Dev@Ratis, I am trying to use jetty as a proxy server, so I could let the ratis server talk to another ratis server through jetty server instead of a ratis server talking directly to another ratis server. But right now have some issues.
Ratis-9000 -> Jetty-8090 ->Ratis-9001 Ratis-9001 -> Jetty-8091 ->Ratis-9000 1. I now have an error message when they are at the stage of leader election when starting. Seems due to this issue after upgrading netty https://github.com/grpc/grpc-java/issues/7953 <https://github.com/grpc/grpc-java/issues/7953> java.lang.UnsupportedOperationException at io.grpc.netty.AbstractHttp2Headers.setLong(AbstractHttp2Headers.java:465) at io.grpc.netty.AbstractHttp2Headers.setLong(AbstractHttp2Headers.java:26) at io.netty.handler.codec.http2.DefaultHttp2ConnectionDecoder$FrameReadListener.onHeadersRead(DefaultHttp2ConnectionDecoder.java:403) at io.netty.handler.codec.http2.DefaultHttp2ConnectionDecoder$FrameReadListener.onHeadersRead(DefaultHttp2ConnectionDecoder.java:347) at io.netty.handler.codec.http2.DefaultHttp2ConnectionDecoder$PrefaceFrameListener.onHeadersRead(DefaultHttp2ConnectionDecoder.java:707) I guess there are 2 approaches that I could try, one is downgrading netty locally, the other one is modify over jetty(which I have no clue on how to fix at this moment) So I tried to downgrade netty locally on the ratis-thirdparty code first. But there is a thing, I tried building the ratis-thirdparty code first before any changes, but I won’t be able to build locally, and the documentation of how to build this code is not much information. I ran “mvn clean install -DskipTests” at the root dir of ratis-thridparty project. But it has been having the below issue: [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project ratis-thirdparty-test: Compilation failure [ERROR] /Users/dhu/Desktop/ratis-thirdparty/test/target/generated-sources/org/apache/ratis/thirdparty/demo/GreeterGrpc.java:[7,18] cannot find symbol [ERROR] symbol: class Generated [ERROR] location: package javax.annotation 2. In addition, I use google’s protoc to generate java files from my custom .proto file. But I then have to manually change ‘com.google.protobuf’ to ‘org.ratis.thirdparty.com.google.protobuf’ since it could not detect com.google.protobuf is the same as the ratis third party one. Is there a way to make this convenient? Like a ratis.thirdparty.protoc ? Or how did ratis build those proto java files? Sincerely, Danielle Hu
