             Summary: Remove one of the gperftools tcmalloc thread cache metrics
                 Key: IMPALA-15021
                 URL: https://issues.apache.org/jira/browse/IMPALA-15021
             Project: IMPALA
          Issue Type: Task
          Components: Backend
    Affects Versions: Impala 5.0.0
            Reporter: Joe McDonnell


In IMPALA-14874, we added additional gperftools TCMalloc metrics. This included both tcmalloc.current-total-thread-cache-bytes and tcmalloc.thread-cache-free-bytes, which map down to the gperftools metrics tcmalloc.current_total_thread_cache_bytes and tcmalloc.thread_cache_free_bytes respectively. Inside the gperftools code, these are actually the same counter, so we can remove one.
