[jira] [Created] (ACCUMULO-2225) Need to better handle DNS failure
propagation from Hadoop
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.
