cdh version 5.7.6, cm version 5.7.2
This morning, I was installing Livy on the cluster, changed some configuration, tried to restart the whole cluster, then the YARN service could not start, tried many times, and always reported errors, but I found all the configurations, and did not find spark_shuffle.
What happened? can anyone help me ？
---error info ------
This seems to be a known issue which was fixed on CM 5.8 and CDH 5.7.1. In your environment, please try to upgrade your CM version to 5.8.5, which was a stable version for CM 5.8.
Hope that helps.
It is nice to hear that.
A side node: CM version 5.7.6 is a stable release for CM 5.7. If you don't plan to upgrade to next major release then you may want to consider to upgrade to CM 5.7.6 version atleast.
Have a good day.
