andygrove opened a new pull request #29494: URL: https://github.com/apache/spark/pull/29494
### What changes were proposed in this pull request? Make MapOutputTracker.getStatistics thread-safe and deterministic. ### Why are the changes needed? We have unit tests such as the skewed join tests in AdaptiveQueryExecSuite that depend on the output being deterministic, and intermittent failures in these tests led me to track this bug down. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Manual testing confirmed that it fixed the intermittent failures. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
