Adar Dembo updated KUDU-2495: ----------------------------- Component/s: project-infra > dist-test slave environment can no longer ptrace > ------------------------------------------------ > > Key: KUDU-2495 > URL: https://issues.apache.org/jira/browse/KUDU-2495 > Project: Kudu > Issue Type: Bug > Components: project-infra, test > Affects Versions: n/a > Reporter: Adar Dembo > Assignee: Todd Lipcon > Priority: Major > > Noticed this while debugging an unrelated failure. I'm guessing it's due to > the VM upgrade in the dist-test environment? We should probably configure > /proc/sys/kernel/yama/ptrace_scope in the host OS so that we can restore this > functionality. > {noformat} > I0710 23:27:16.445466 18604 external_mini_cluster-itest-base.cc:86] > Attempting to dump stacks of TS 0 with UUID 3576d2baa86141439f2e837433589a9b > and pid 22014 > ************************ BEGIN STACKS ************************** > Could not attach to process.
