Patch Set 2: No, I do not feel strongly about this. > > Should any startup scripts be modified to trap '' SIGUSR1 before > > launching the daemons since there is still technically a race > from > > daemon startup to when the mini-dump signal handler is > registered? > > (Though from what I can tell the typical usage of the SIGUSR1 > > mini-dump handler would very likely never encounter this race, so > > maybe not worth fixing?) > > Yes, that race exists, I don't think it's worth fixing though. > Human operators should not hit it. Automated scripts that regularly > trigger minidumps sending SIGUSR1 could hit this, but I think we > should not encourage those anyways. Let me know if you feel > strongly about this. -- To view, visit http://gerrit.cloudera.org:8080/7631 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: I13d866a2eec832500131954a7f693c33585ea51e Gerrit-PatchSet: 2 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Lars Volker <l...@cloudera.com> Gerrit-Reviewer: John Sherman <j...@arcadiadata.com> Gerrit-Reviewer: Lars Volker <l...@cloudera.com> Gerrit-Reviewer: Sailesh Mukil <sail...@cloudera.com> Gerrit-HasComments: No
