Jinjiang Ling created YARN-6837:
-----------------------------------
Summary: When the LocalResource's visibility is null, the
NodeManager will shutdown
Key: YARN-6837
URL: https://issues.apache.org/jira/browse/YARN-6837
Project: Hadoop YARN
Issue Type: Bug
Reporter: Jinjiang Ling
When I write an yarn application, I create a LocalResource like this
{quote}
LocalResource resource = Records.newRecord(LocalResource.class);
{quote}
Because I forget to set the visibilty of it, so the job is failed when I submit
it.
But NodeManager shutdown one by one at the same time, and there is
NullPointerExceptionin NodeManager's log:

{quote}
Then I change my code and still set the visibility to null
{quote}
LocalResource resource = LocalResource.newInstance(
URL.fromURI(dst.toUri()),
LocalResourceType.FILE, {color:red}null{color},
fileStatus.getLen(),
fileStatus.getModificationTime());
{quote}
This error still happen.
At last I set the visibility to correct value, the error do not happen again.
So I think the visibility of LocalResource is null will cause NodeManager
shutdown.
