--------------------------------
Summary: Possible data races in util/trace
Key: KUDU-1624
URL: https://issues.apache.org/jira/browse/KUDU-1624
Project: Kudu
Issue Type: Bug
Components: util
Affects Versions: 1.0.0
Reporter: Adar Dembo
Attachments: rpc_stub-test.txt
I'm running clang 3.9 against a Kudu source tree using libcpp, so it's possible
this is partly due to differences in how libstdc++ implements std::vector. Or
maybe it's real.
At first glance, it looks like the problem is that
Trace::MetricsToJSON(JsonWriter*) doesn't hold lock_ while accessing
child_traces_. It would need to some refactoring to avoid taking lock_
recursively, though, since it's a recursive function.
