Daniel Templeton commented on YARN-7383:
----------------------------------------
The docs don't say a whole lot, but I would assume that '.' is not a valid
character for a resource name. CC: [~leftnoteasy], [~sunilg]
> Node resource not parsed correctly for resource names containing dot
> --------------------------------------------------------------------
>
> Key: YARN-7383
> URL: https://issues.apache.org/jira/browse/YARN-7383
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager, resourcemanager
> Reporter: Jonathan Hung
>
> Currently when getting resource capabilities in {{node-resources.xml}}, the
> following parsing code is used: {noformat} String[] parts =
> prop.split("\\.");
> LOG.info("Found resource entry " + prop);
> if (parts.length == 4) {
> String resourceType = parts[3];
> if (!nodeResources.containsKey(resourceType)) {
> nodeResources
> .put(resourceType, ResourceInformation.newInstance(resourceType));
> }
> String units = getUnits(value);
> Long resourceValue =
> Long.valueOf(value.substring(0, value.length() - units.length()));
> nodeResources.get(resourceType).setValue(resourceValue);
> nodeResources.get(resourceType).setUnits(units);
> if (LOG.isDebugEnabled()) {
> LOG.debug("Setting value for resource type " + resourceType + " to "
> + resourceValue + " with units " + units);
> }
> }{noformat}
> If resource names contain dots though (e.g. for resource names in a
> namespace) this will not parse correctly.
