Patch Set 1: > Does Impala just shutdown if you try starting it on Opeteron Rev E > today ? In practice, yes (because we execute SSSE3 instructions). It's a little indirect because some EC2 instances mask SSSE3 CPUID even though the physical CPU is capable, and people want to be able to run Impala on those instances, so we only print a warning about SSSE3 missing, but then try anyway (even though, as you know, this isn't the best practice from a VM usage standpoint). -- To view, visit http://gerrit.cloudera.org:8080/2516 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: I3639dcf86c14778967c0079b8dbc222a4516cf05 Gerrit-PatchSet: 1 Gerrit-Project: Impala Gerrit-Branch: cdh5-trunk Gerrit-Owner: Dan Hecht <[email protected]> Gerrit-Reviewer: Dan Hecht <[email protected]> Gerrit-Reviewer: Henry Robinson <[email protected]> Gerrit-Reviewer: Michael Ho <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-HasComments: No
