Subject [jira] [Updated] (HDFS-10630) Federation State Store FS Implementation
Date Fri, 14 Apr 2017 02:26:41 GMT

     [ https://issues.apache.org/jira/browse/HDFS-10630?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Inigo Goiri updated HDFS-10630:
    Attachment: HDFS-10630-HDFS-10467-006.patch

Tackling [~chris.douglas] comments:
* The {{StateStoreFileImpl}} is basically for unit testing but it can be used with NFS or
similar to make it available to other Routers. The {{StateStoreFileSystemImpl}} can rely on
HDFS for the State Store.
* Fixed {{StateStoreConnectionMonitorService}}.
* Fixed {{PeriodicService}}.
* Originally I shared the {{StateStoreService}} with the metrics systems, etc. I changed it
to just pass the State Store properly.
* Switched the {{StateStoreUtils}} reflection methods into {{Query}}.
