Hi all, I am interested in instrumenting Spark with OpenTracing to get good user level infirmation about the tasks being executed.
I started doing some work, mainly in TransportClient and TransportRequestHandler, to start OpenTracing spans when sending an RpcRequest and finish the spans in a modified callback. I am also able to propagate the context once by storing Span information into the byte array that is sent to the server. However, I am not able to propagate the context further. What happens if the handler on the server side emits another request and I want to start a new span that is causally related to the last one? I didn’t find an easy way to have access to the « parent request » information in the TransportClient. Am I missing something? Any help would be appreciated!
