This problem surfaced in impala integration tests IMPALA-11592. TestLocalCatalogRetries.test_fetch_metadata_retry fails in S3 build after the change HADOOP-17461. Add thread-level IOStatistics Context The actual GC race condition came with HADOOP-18091. S3A auditing leaks memory through ThreadLocal references The fix for this is, if our hypothesis is correct, in WeakReferenceMap.create() where a strong reference to the new value is kept in a local variable *and referred to later* so that the JVM will not GC it. Along with the fix, extra assertions ensure that if the problem is not fixed, applications will fail faster/more meaningfully. Contributed by Steve Loughran. |
