Steve Loughran commented on HADOOP-5348:
----------------------------------------
Needs of HADOOP-5201
# Ability to construct new StackTraceElement lists from stack traces (i,e. do
not downconvert to text)
# ability to create a new exception from a deserialized exception, with
toString(), stack trace &c recreating the details received
# Option of using error codes
> Create a stable wire format for exceptions

> Key: HADOOP-5348
> URL: https://issues.apache.org/jira/browse/HADOOP-5348
> Project: Hadoop Core
> Issue Type: New Feature
> Components: ipc
> Affects Versions: 0.20.0, 0.21.0
> Reporter: Steve Loughran
> Attachments: ThrowableWritable.java
>
>
> 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.
