Subject [jira] Commented: (HADOOP-5348) Create a stable wire format for exceptions
Date Fri, 27 Feb 2009 11:39:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5348?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12677329#action_12677329
] 

Steve Loughran commented on HADOOP-5348:
----------------------------------------

This could also be used in the ping operations proposed in HADOOP-3628; these objects would
be lighter weight than a list of exceptions if there was no need to create stack traces, but
easy to marshall

> HADOOP-5201 and other issues would benefit from a stable representation of exceptions,
one that can be sent over the network, maybe pushed out to web UIs and which we can be 100%
sure that the far end will be able to handle if they have the hadoop-core JAR on their classpath.
