Subject [jira] [Updated] (HDFS-10629) Federation Router
Date Tue, 28 Mar 2017 02:20:41 GMT

     [ https://issues.apache.org/jira/browse/HDFS-10629?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Inigo Goiri updated HDFS-10629:
-------------------------------
    Attachment: HDFS-10629-HDFS-10467-012.patch

Renamed {{FederationStateStoreService}} to {{StateStoreService}}.

Tackled most [~chris.douglas] comments:
* Fixed {{FederationNamenodeServiceState}}
* {{RouterConfigBuilder}} right now is very basic, but we will add new config settings once
we add services to the {{Router}}
* The {{restartRpcServer()}} functionality was only internal debuggin, so removed it
* Clarified {{RemoteLocationContext#getDest()}}
* {{ReflectionUtils#newInstance}} doesn't support parameter passing, and this is a pretty
common pattern for our use case. We use the {{getClass()}} already and I'm not sure adding
the creation of a simple constructor adds much
* Made list return unmodifiable in {{PathLocation}}
