Subject [jira] [Created] (ACCUMULO-2225) Need to better handle DNS failure propagation from Hadoop
Date Mon, 20 Jan 2014 17:40:23 GMT
Sean Busbey created ACCUMULO-2225:
-------------------------------------

             Summary: Need to better handle DNS failure propagation from Hadoop
                 Key: ACCUMULO-2225
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2225
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.5.0, 1.4.4
         Environment: 1.4.5-SNAP on CDH4 w/gremlins
            Reporter: Sean Busbey
            Assignee: Sean Busbey
             Fix For: 1.4.5, 1.5.1, 1.6.0


Injecting network failures to cause dns failures can cause odd failures within our underlying
Hadoop calls such that IllegalArgumentExceptions come out (rather than IOException or UnknownHostException).

There are several places where we do not adequately account for this, causing role failure.
