[jira] [Created] (KAFKA-12509) Tighten up StateDirectory thread locking

A. Sophie Blee-Goldman created KAFKA-12509:
----------------------------------------------

             Summary: Tighten up StateDirectory thread locking
                 Key: KAFKA-12509
                 URL: https://issues.apache.org/jira/browse/KAFKA-12509
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: A. Sophie Blee-Goldman


The StateDirectory class is responsible for tracking the ownership of task directories, which may be locked by StreamThreads, the cleaner thread, or a user thread via KafkaStreams.cleanup(). It maintains a map from TaskId to the name of the owning thread. 

We should consider tightening this up a bit and using a reference to the actual Thread instead of just the name.
