[jira] [Created] (YARN-5758) NodeStatusUpdaterImpl serviceInit can
NPE if ResourcePlugin is null
Kuhu Shukla created YARN-5758:
---------------------------------
Summary: NodeStatusUpdaterImpl serviceInit can NPE if ResourcePlugin is null
Key: YARN-5758
URL: https://issues.apache.org/jira/browse/YARN-5758
Project: Hadoop YARN
Issue Type: Bug
Environment: OS X Yosemite 10.10.3
Reporter: Kuhu Shukla
Assignee: Kuhu Shukla
Running {{TestNodeStatusUpdaterForLabels#testInvalidNodeLabelsFromProvider}},
{{testNodeStatusUpdaterForNodeLabels}}
on MAC causes NullPointerException as the ResourcePlugin returns null,
We should protect against that in NodeStatusUpdaterImpl#serviceInit:
{code}
// Get actual node physical resources
ResourceCalculatorPlugin rcp =
ResourceCalculatorPlugin.getResourceCalculatorPlugin(null, conf);
int physicalMemoryMb = (int) rcp.getPhysicalMemorySize() / (1024 * 1024);
{code}
