--------------------------------------
Great catch, Billie!
> NamingThreadFactory.newThread should not wrap runnable with TraceRunnable
> -------------------------------------------------------------------------
>
> Key: ACCUMULO-3507
> URL: https://issues.apache.org/jira/browse/ACCUMULO-3507
> Project: Accumulo
> Issue Type: Bug
> Components: trace
> Reporter: Billie Rinaldi
> Assignee: Billie Rinaldi
> Fix For: 1.7.0
>
>
> NamingThreadFactory has the following implementation of newThread:
> {noformat}
> public Thread newThread(Runnable r) {
> return new Daemon(new LoggingRunnable(log, new TraceRunnable(r)), ...);
> }
> {noformat}
> The runnable passed to newThread by ThreadPoolExecutor is a Worker that will
> run multiple tasks over its lifetime. It is unlikely that we want to trace
> the entire execution of a reused thread in one of our thread pools, as
> opposed to tracing individual tasks. We should change this to new
> LoggingRunnable(log, r).
> Some of our thread pools already trace individual tasks by wrapping a
> ThreadPoolExecutor in TraceExecutorService. Other pools that want to
> introduce task tracing may use that method as well. (The pools currently
> tracing threads but not tracing tasks are scanner read ahead, add splits,
> bloom loader, LRU block cache stats, gc deleting, walog sort starter,
> multiple bulk import pools, problem reporting, and others that are using
> SimpleThreadPool.)
