    Description

      There should be a way for clients to link the runtime profiles from failed queries to all retry attempts (whether successful or not), and vice versa.

      There are a few ways to do this:

      • The simplest way would be to include the query id of the retried query in the runtime profile of the failed query, and vice versa; users could then manually create a chain of runtime profiles in order to fetch all failed / successful attempts
      • Extend TGetRuntimeProfileReq to include an option to fetch all runtime profiles for the given query id + all retry attempts (or add a new Thrift call TGetRetryQueryIds(TQueryId) which returns a list of retried ids for a given query id)
      • The Impala debug UI should include a simple way to view all the runtime profiles of a query (the failed attempts + all retry attempts) side by side (perhaps the¬†query_profile?query_id profile should include tabs to easily switch between the runtime profiles of each attempt)

      These are not mutually exclusive, and it might be good to stage these changes.
