---------------------------------------

             Summary: minidump-test is flaky
                 Key: IMPALA-11291
                 URL: https://issues.apache.org/jira/browse/IMPALA-11291

          Issue Type: Bug
            Reporter: Quanlong Huang
            Assignee: Quanlong Huang


Minidump.DumpCallback and Minidump.DumpCallbackWithThread added by IMPALA-11275 are flaky.

Minidump.DumpCallback is found to fail in an unrelated build:
https://jenkins.impala.io/job/ubuntu-16.04-from-scratch/16449/testReport/junit/(root)/Minidump/DumpCallback/
{noformat}
/home/ubuntu/Impala/be/src/util/minidump-test.cc:47
Value of: lines.size()
  Actual: 4
Expected: 3
{noformat}

While looping the test locally, I can also find failures of DumpCallbackWithThread:
