Subject [jira] Updated: (HADOOP-6220) HttpServer wraps InterruptedExceptions by IOExceptions if interrupted in startup
Date Fri, 04 Feb 2011 15:14:28 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-6220?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Steve Loughran updated HADOOP-6220:

    Affects Version/s: 0.22.0
               Status: Patch Available  (was: In Progress)

this is the existing patch, instead of just throwing an IOException when startup is interrupted,
it gets converted to an InterruptedIOException

> Following on some discusson on mapred-dev, we should keep an eye on the fact that Jetty
uses sleeps when starting up; jetty can be a big part of the delays of bringing up a node.
When interrupted, the exception is wrapped by an IOException, the root cause is still there,
just hidden.
> If we want callers to distinguish InterruptedExceptions from IOEs, then this exception
should be extracted. Some helper method to start an http daemon could do this -catch the IOE,
and if there is a nested interrupted exception, rethrow it, otherwise rethrowing the original
