Please visit http://gerrit.cloudera.org:8080/3312 to look at the new patch set (#4). Change subject: IMPALA-3677: Write minidump on SIGUSR1 ...................................................................... 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 --- M be/src/util/minidump.cc M tests/custom_cluster/test_breakpad.py 2 files changed, 53 insertions(+), 6 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala refs/changes/12/3312/4 -- To view, visit http://gerrit.cloudera.org:8080/3312 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newpatchset Gerrit-Change-Id: I40149e48e391451de21a5c8bda18e2307fc89513 Gerrit-PatchSet: 4 Gerrit-Project: Impala Gerrit-Branch: cdh5-trunk Gerrit-Owner: Lars Volker Gerrit-Reviewer: David Knupp Gerrit-Reviewer: Lars Volker Gerrit-Reviewer: Tim Armstrong
