wtf updated DRILL-8059:
-----------------------
Description:
One of the minor fragment starts late sometimes. All fragments transterred
between the same node pair take muck longer time during that period.
Three profiles attached. The slow communication happens around
11:45:18~11:45:38 between node explorersha-49-7146.ET15.alipay.com and node
explorersha-49-6019.ET15.alipay.com.
