Íñigo Goiri commented on HDFS-15075:
------------------------------------
[~hexiaoqiao], thought here?
I am referring to:
{code}
long startProcessCommands = monotonicNow();
commandProcessingThread.enqueue(resp.getCommands());
long endProcessCommands = monotonicNow();
if (endProcessCommands - startProcessCommands > 2000) {
LOG.info("Took " + (endProcessCommands - startProcessCommands)
+ "ms to process " + resp.getCommands().length
+ " commands from NN");
}
{code}
We may want to do this timing in CommandProcessingThread now and maybe track
this times in a counter.
> Remove process command timing from BPServiceActor

> HDFS-14997 moved the command processing into async.
> Right now, we are checking the time to add to a queue.
> We should remove this one and maybe move the timing within the thread.
