Patch Set 1: This addresses all the header comments in the non-header only patch: (i.e. https://gerrit.cloudera.org/#/c/3817/) I will post a compilable version of this patch in that CR. That will be a lot more tricky mainly because: - PlanFragmentExecutor and FragmentExecState are now one class. This makes the coordinator code tricky because the Coordinator had special code which depended only on the PFE and not on the FES; and has redundant FES functionality to manage the PFE. @Lars: This patch can be used as a guide for the per-query RPC (IMPALA-2550), and also for working out the final kinks in the headers. -- To view, visit http://gerrit.cloudera.org:8080/4301 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: If58292a5c377660d97e7e7cc0c3122328eba72ed Gerrit-PatchSet: 1 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Sailesh Mukil <sail...@cloudera.com> Gerrit-Reviewer: Sailesh Mukil <sail...@cloudera.com> Gerrit-HasComments: No
