Sijie Guo commented on BOOKKEEPER-689:
--------------------------------------
I don't think this is an issue in bookkeeper client.
[ pool size = 0, active threads = 0, queued tasks = 1, completed tasks = 0 ].
pool size & active threads are 0 means there is no worker thread in the
executor. and completed tasks is 0 means there is no tasks is executed. it
looks like a race condition in add & shutdown of executor, so the task is
queued and but no work thread to execute.
since bookkeeper#close takes up to 10 seconds, the bookkeeper test should wait
more than 10 seconds until bookkeeper#close finished.
{code}
public String toString() {
long ncompleted;
int nworkers, nactive;
final ReentrantLock mainLock = this.mainLock;
mainLock.lock();
try {
ncompleted = completedTaskCount;
nactive = 0;
nworkers = workers.size();
for (Worker w : workers) {
ncompleted += w.completedTasks;
if (w.isLocked())
++nactive;
}
} finally {
mainLock.unlock();
}
int c = ctl.get();
String rs = (runStateLessThan(c, SHUTDOWN) ? "Running" :
(runStateAtLeast(c, TERMINATED) ? "Terminated" :
"Shutting down"));
return super.toString() +
"[" + rs +
", pool size = " + nworkers +
", active threads = " + nactive +
", queued tasks = " + workQueue.size() +
", completed tasks = " + ncompleted +
"]";
