Subject [jira] [Updated] (HDFS-10881) Federation State Store Driver API
Date Sat, 25 Mar 2017 02:08:42 GMT

     [ https://issues.apache.org/jira/browse/HDFS-10881?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Inigo Goiri updated HDFS-10881:
    Attachment: HDFS-10881-HDFS-10467-010.patch

Tackling most [~subru]'s comments.
I made everything just to be interfaces and a simple implementation so no unit tests yet.

I still have pending the naming approach. I tried to follow the YARN federation naming convention
but I wasn't sure in many cases. I would vote for removing the Federation prefix but YARN
federation does otherwise. I think we will have some clashes anyway but hopefully those will
be private classes.
