IMPALA-3677: Write minidump on SIGUSR1 Sending SIGUSR1 to any of the impala daemons (catalogd, impalad, statestored) will trigger a minidump write. The hotspot JVM also uses SIGUSR1 internally. However the documentation explains, that existing signal handlers will be transparently wrapped by the JVM and no spurious signals should be received by the daemon signal handler: http://www.oracle.com/technetwork/java/javase/signals-139944.html Example: killall -SIGUSR1 catalogd Change-Id: I40149e48e391451de21a5c8bda18e2307fc89513 Reviewed-on: http://gerrit.cloudera.org:8080/3312 Reviewed-by: Lars Volker <[email protected]> Tested-by: Internal Jenkins --- M be/src/util/minidump.cc M tests/custom_cluster/test_breakpad.py 2 files changed, 74 insertions(+), 10 deletions(-) Approvals: Lars Volker: Looks good to me, approved Internal Jenkins: Verified -- To view, visit http://gerrit.cloudera.org:8080/3312 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: merged Gerrit-Change-Id: I40149e48e391451de21a5c8bda18e2307fc89513 Gerrit-PatchSet: 10 Gerrit-Project: Impala Gerrit-Branch: cdh5-trunk Gerrit-Owner: Lars Volker <[email protected]> Gerrit-Reviewer: Dan Hecht <[email protected]> Gerrit-Reviewer: David Knupp <[email protected]> Gerrit-Reviewer: Internal Jenkins Gerrit-Reviewer: Lars Volker <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]>
