[jira] [Updated] (TS-4436) ATS' tracking of host failures is broken for entries acquired through the hosts file

["Thomas Jackson (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TS-4436?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Jackson updated TS-4436:
-------------------------------
    Description: The current implementation of the hosts file maintains a map of name to hostdbinfo, which means that any lookups that come into the probe method return the same hostdbinfo struct. This means that any requests to a given address (regardless of port) recieve the same HostDBInfo struct-- which in turn means that the up/down status is global to the IP instead of per ip/port pair.  (was: The current implementation of the hosts file maintains a map of name -> hostdbinfo, which means that any lookups that come into the probe method return the same hostdbinfo struct. This means that any requests to a given address (regardless of port) recieve the same HostDBInfo struct-- which in turn means that the up/down status is global to the IP instead of per ip/port pair.)
