Patch Set 1: (1 comment) http://gerrit.cloudera.org:8080/#/c/6768/1//COMMIT_MSG Commit Message: PS1, Line 17: memcmp is sse4.1-based > Oops, yeah cmp. OK. Can you be specific about the benchmarks you'd like to see run, to avoid to many iterations of this patch set, including any node configuration or scale factor or file type restrictions you will require? As a heads-up: I am not in a position to spend a lot of time setting up benchmarks that don't work out-of-the box with Apache Impala on a single node, so I may have to pass this off to someone else or just submit this change to the benchmark and let somebody else finish it if what you need requires more time than I have. -- To view, visit http://gerrit.cloudera.org:8080/6768 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: Ie4786a4a75fdaffedd6e17cf076b5368ba4b4e3e Gerrit-PatchSet: 1 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Jim Apple <[email protected]> Gerrit-Reviewer: Dan Hecht <[email protected]> Gerrit-Reviewer: Jim Apple <[email protected]> Gerrit-Reviewer: Mostafa Mokhtar <[email protected]> Gerrit-HasComments: Yes
