Subject [jira] [Created] (YARN-7383) Node resource not parsed correctly for resource names containing dot
Date Tue, 24 Oct 2017 00:08:00 GMT
Jonathan Hung created YARN-7383:
-----------------------------------

             Summary: 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
            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.
