Hey folks, Since 0.9 was released, we've run into a couple issues that have impacted both test clusters and a real-life cluster at JD.com:
- a bug in tcmalloc-related metrics caused writes into already-freed memory which could cause lots of different crashes under load ( https://gerrit.cloudera.org/#/c/3445/) - a bug in Raft which could cause a tablet to get "stuck" and cease to make progress after a leader election (KUDU-1469, fix in review at https://gerrit.cloudera.org/#/c/3228/ ) The first of these in particular is a regression since 0.8 and is pretty critical (can cause crashes, incorrect data getting persisted, etc). So, I think we should try to address these issues with a patch release (0.9.1) ASAP. Thoughts? Anything else that we should consider as a candidate for 0.9.1? -Todd -- Todd Lipcon Software Engineer, Cloudera
