Subject [jira] [Updated] (MAPREDUCE-4198) Update RackResolver and related tests to resolve host with new API from HADOOP-8304 (DNSToSwitchMapping should add interface to resolve individual host besides a list of host)
Date Sun, 01 Jul 2012 10:50:45 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4198?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Junping Du updated MAPREDUCE-4198:
----------------------------------

    Resolution: Won't Fix
        Status: Resolved  (was: Patch Available)

>From Hadoop-8304, the interfaces for resolving hosts is a tradeoff between convenient
and compatible. Currently, our choice is to keep compatibility so close this issue as "Won't
fix" now.
