-------------------------------------
Hi [~szetszwo], Recently I did performance test on streaming use pipline model.
Here are my results([test
doc|https://docs.google.com/document/d/1crXT4BE8ueRakddiVoVl7E_BH--FcU54YWeThHOx2Lg/edit?usp=sharing]):
!screenshot-4.png!
The fastest performance I measured was 57872 ms, which is very close to HDFS's
54292ms.
But it can also be very slow, although not very often. At this time, I find
that datanode always generates a lot of timeout WARNS.
There is very little feedback in the log and I am wondering how to avoid this
kind of problem. Do you have any suggestions?
