After upgrade our cluster to version 5.7 livy-spark-server failed to start, on 5.4.8 it worked fine.
In log file we see the following error:
"Error: Could not find or load main class com.cloudera.hue.livy.server.Main"
[root@*-dev-01]# service livy-spark-server start Starting livy-spark-server... OK [root@*-dev-01]# service livy-spark-server status livy-spark-server is dead but pidfile /var/run/livy-spark-server.pid exists
Do anyone have the same problem after upgrade and maybe know how to overcome it?
