Subject [jira] [Commented] (HADOOP-7821) Hadoop Messaging Service
Date Wed, 16 Nov 2011 10:32:53 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7821?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13151125#comment-13151125

Steve Loughran commented on HADOOP-7821:
----------------------------------------

I'd go for some plugin points and see how they get used. Distributed messaging services are
hard to get right or scale -and problems that other projects have worked on.

while an in-VM event mechanism would be tractable, especially if the events were queued to
decouple event from plugin notification from day one. Then I could do a bridge to push events
into our partition-aware T-space; other people can push them into ActiveMQ, Kafka or anything
else.

> It will be good if Hadoop supports some sort of a messaging service that allows users
to subscribe.
