LogMessage
Key: YARN-11334
URL: https://issues.apache.org/jira/browse/YARN-11334
Project: Hadoop YARN
Issue Type: Improvement
Components: federation
Affects Versions: 3.4.0
Reporter: fanshilun
Assignee: fanshilun
The SubClusterState object has a fromString method, which can be improved in
the following 2 places
{code:java}
/**
* Convert a string into {@code SubClusterState}.
*
* @param x the string to convert in SubClusterState
* @return the respective {@code SubClusterState}
*/
public static SubClusterState fromString(String x) {
try {
return SubClusterState.valueOf(x);
} catch (Exception e) {
LOG.error("Invalid SubCluster State value in the StateStore does not"
+ " match with the YARN Federation standard.");
return null;
}
} {code}
* The parameter is named x, which cannot well express the meaning of the input
parameter.
* The error log does not print the error value.
