Subject Re: some spout executor complete latency very high
Date Mon, 27 Feb 2017 03:38:25 GMT
You're running 20 executors in one machine. Does the machine have enough
cores so that it can run 'really' parallel?
(Where spouts pull the data? If it doesn't involve CPU much it will be OK,
but where bolts are placed affects the issue.)
And how much ackers topology has, and which workers ackers being placed?

Please examine CPU, memory, GC, IO for that machine to ensure there's no
resource issue.
And check your topology physical plan, how spouts/bolts are placed and how
they're connected.
Try profiling to bad workers and see if there's memory leak issue, CPU go
high, GC too much, etc.

Hope this helps.

Thanks,
