[jira] [Commented] (PIG-2660) PPNL should get notified of plan
before it gets executed
[ https://issues.apache.org/jira/browse/PIG-2660?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13262117#comment-13262117 ]
Alan Gates commented on PIG-2660:
---------------------------------
Looks good. Do we have any idea how often people implement PigProgressNotificationListerner? I'm wondering if the calls to initialPlanNotfication in SyncProgressNotificationAdaptor and ScriptState should be wrapped with a catch for NoSuchMethodException in case people are using old listeners. Other than that, +1.

> The {{PigProgressNotificationListner}} should get notified of the plan ({{MROperPlan}}) before it gets executed. This allows listeners to inspect the plan and have an idea what to expect in the execution flow. Proposal is to add the following method to the PPNL interface, which is marked as evolving:
> {code}
> public void initialPlanNotification(MROperPlan plan);
> {code}
