Tim Armstrong updated IMPALA-10142:
-----------------------------------
Component/s: Distributed Exec
> Add RPC sender tracing
> ----------------------
>
> Key: IMPALA-10142
> URL: https://issues.apache.org/jira/browse/IMPALA-10142
> Project: IMPALA
> Issue Type: Improvement
> Components: Distributed Exec
> Reporter: Sahil Takiar
> Priority: Major
>
> We currently have RPC tracing on the receiver side, but not on the the sender
> side. For slow RPCs, the logs print out the total amount of time spent
> sending the RPC + the network time. Adding tracing will basically make this
> more granular. It will help determine where exactly in the stack the time was
> spent when sending RPCs.
> Combined with the trace logs in the receiver, it should be much easier to
> determine the timeline of a given slow RPC.
