Adds a new map type WeakReferenceMap, which stores weak references to values, and a WeakReferenceThreadMap subclass to more closely resemble a thread local type, as it is a map of threadId to value. Construct it with a factory method and optional callback for notification on loss and regeneration. WeakReferenceThreadMap<WrappingAuditSpan> activeSpan = new WeakReferenceThreadMap<>( (k) -> getUnbondedSpan(), this::noteSpanReferenceLost); This is used in ActiveAuditManagerS3A for span tracking. Relates to * HADOOP-17511. Add an Audit plugin point for S3A * HADOOP-18094. Disable S3A auditing by default. Contributed by Steve Loughran. |
