[jira] Updated: (HADOOP-430) http server should die if the Datanode fails.

     [ http://issues.apache.org/jira/browse/HADOOP-430?page=all ]

Wendy Chien updated HADOOP-430:
-------------------------------

    Attachment: hadoop-430.patch

This patch checks if the datanode registration has failed.  If it has, it stops the http server.

> HADOOP-375 changed the order in which a data node registers and starts its http server.
> Current version first starts the http server, then registers. As a result if the registration fails,
> which can happen e.g. if the datanode has illegal storage id (=does not belong to the cluster),
> the http server keeps running, which makes the data node seem running too.
> I think 2 things need to be done.
> 1) Datanode registration should precede the http server startup.
> 2) The http server should shutdown when the datanode fails (in general).
> I am attaching a patch for the first item.
> Does anybody know how the latter can be done in the version of jetty we are on now?
