Subject [jira] [Updated] (HDFS-2452) OutOfMemoryError in DataXceiverServer takes down the DataNode
Date Thu, 20 Oct 2011 22:22:11 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2452?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Konstantin Boudnik updated HDFS-2452:
-------------------------------------

    Attachment: HDFS-2452-22branch_with-around_.patch

Uma, we can throw an exception instead of calling run() method. In this case before(...):
advice has to be replaced with void around(...): one (see new patch).

Or, doing this before invoking run() means that it should be happening in DataXceiverServer,
right? They the patch needs to be slightly different and we need to instrument DataXceiverServer
instead of DataXceiver. Sorry, I am confused.
