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 ------
Start a role
Role failed to start due to error com.cloudera.cmf.service.config.ConfigGenException: Conflicting yarn extensions of key [spark_shuffle].
