drcrallen opened a new issue #6024: Missing exception handling as part of `io.druid.java.util.http.client.netty.HttpClientPipelineFactory`
URL: https://github.com/apache/incubator-druid/issues/6024
 
 
   The `io.druid.java.util.http.client.netty.HttpClientPipelineFactory` class constructs the netty pipeline for handling request channels. But whenever an exception happens in reading (for example a historical shuts down during a query) The following log line is printed in the logs:
   
   
   ```
   EXCEPTION, please implement org.jboss.netty.handler.codec.http.HttpContentDecompressor.exceptionCaught() for proper handling.
   ```
   
   As can be seen in `org.jboss.netty.channel.SimpleChannelUpstreamHandler#exceptionCaught`
   
   This ask is that "proper" exception handling be implemented in the http client workflow such that the logs do not have such an error when there are exceptions in the netty channel.
