MENG DING commented on YARN-3866:
---------------------------------
* The FindBugs doesn't seem to be working in YARN-1197 branch (My own tests
work fine though)
* The checkstyle issues are false alarms. They are needed for Javadocs to work
{code:title=ContainerResourceChangeRequest.java|borderStyle=solid}
+import org.apache.hadoop.classification.InterfaceAudience.Public;
+import org.apache.hadoop.classification.InterfaceStability.Unstable;
+import org.apache.hadoop.yarn.api.ApplicationMasterProtocol; <-----------
(Needed for Javadoc related method)
+import org.apache.hadoop.yarn.util.Records;

+/**
+ * {@code ContainerResourceChangeRequest} represents the request made by an
+ * application to the {@code ResourceManager} to change resource allocation of
+ * a running {@code Container}.
+ * <p>
+ * It includes:
+ * <ul>
+ * <li>{@link ContainerId} for the container.</li>
+ * <li>
+ * {@link Resource} capability of the container after the resource change
+ * is completed.
+ * </li>
+ * </ul>

+ * @see
ApplicationMasterProtocol#allocate(org.apache.hadoop.yarn.api.protocolrecords.AllocateRequest)
<-------- (can't break this otherwise Javadoc won't work.)
