Subject [jira] [Commented] (YARN-1149) NM throws InvalidStateTransitonException: Invalid event: APPLICATION_LOG_HANDLING_FINISHED at RUNNING
Date Thu, 03 Oct 2013 22:44:43 GMT

    [ https://issues.apache.org/jira/browse/YARN-1149?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13785622#comment-13785622
] 

Hitesh Shah commented on YARN-1149:
-----------------------------------

{code}
+    /**
+     * Application is killed by ResourceManager
+     */
+    ON_SHUTDOWN, 
+
+    /**
+     * Application is killed as NodeManager is shut down
+     */
+    BY_RESOURCEMANAGER
{code}

  -  descriptions reversed 

{code}
+      default:
+        LOG.warn("Invalid eventType: " + eventType);
+    }
{code}

   - earlier comment on invalid event type not addressed? 

{code}
+  @SuppressWarnings("unchecked")
+  static class NonTransition implements
+      SingleArcTransition<ApplicationImpl, ApplicationEvent> {
+    @Override
+    public void transition(ApplicationImpl app, ApplicationEvent event) {
+      if (LOG.isDebugEnabled()) {
+        LOG.debug("The event: " + event.getType()
+            + " is invalid in current state : " + app.getApplicationState());
+      }
+    }
+  }
+
{code}
   
    - may be better to not have a non-transition. Current message reads as if this is an error
and is being ignored with no reason as to why it is ignored.
