hi everyone,
In my topology, my kafkaspout has many problems and I don't know how it
happens
1. the latency is very high , I have 10 kafkaspout and the average latency is
up to 10k ms
2. Failed number is very high, the number of failed is about 50% of emitted
tuple.
3. An error often occurs, the error info is :
