Subject Flink standalone cluster load average is too high.
Date Sat, 29 Sep 2018 05:43:19 GMT
I am using flink 1.5.2 in standalone mode. The machine is 8 cores with 32GB memory. I set slots
to 4 or 8. I set most jobs parallelism to 1. And each machine has jobs less than the slot
number.

The load average is too high as the picture shows below. Each line presents load average 1
on one machine. CPU usage on each machine is 100%. 

All jobs are flink stream SQL. 

  

Can anybody help?


Thanks.
