NodeManager does not start when the naming scheme is not followed

[he-sk]

When the naming scheme is not followed (i.e., yarn.io/gpu instead of yarn.io/gpu-geforcegtx1080), start-yarn.sh prints a cryptic error message:

$ sbin/start-yarn.sh
Starting resourcemanager
Starting nodemanagers
localhost: ERROR: Cannot set priority of nodemanager process 15665

This error is caused by an java.lang.ArrayIndexOutOfBoundsException because the split in the following line does not work as expected. This error should be handled more gracefully.

E2DataYARN/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/java/org/apache/hadoop/yarn/server/nodemanager/containermanager/resourceplugin/ResourcePluginManager.java

Line 92 in 2842739

String productName = resourceName.split("-")[1];

so what is the solution for this
~/hadoop-3.2.3/sbin$ start-yarn.sh
Starting resourcemanager
ERROR: Cannot set priority of resourcemanager process 9834
Starting nodemanagers
localhost: ERROR: Cannot set priority of nodemanager process 9944

@Vasuki-munirathinam Is this Hadoop instance installed through Peel or manually?

[Vasuki-munirathinam]

Yeah it is installed manually and i rectified that error
The oracle jdk version i have used is latest so i switched to 8.1 version.

Does the error also occur when installed through Peel? That is the workflow that we support.
