Subject [jira] [Commented] (HBASE-16727) Refactoring: move MR dependencies from HMaster
Date Wed, 28 Sep 2016 18:50:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15530519#comment-15530519

Vladimir Rodionov commented on HBASE-16727:
-------------------------------------------

We will try to minimize work first.

Backup code is currently split between client and server module. 
# We will not create a separate module for backup unless it will be requested by community.

# Backup/restore code will be removed from Master
# Backup / restore procedures will be converted to utility classes in a *server* module for
command-line driven tools (BackupDriver and RestoreDriver)
# We will need to remove completely BackupAdmin API, because after refactoring it will no
longer be possible to trigger backup/restore   from client module.
# The only backup/ restore API we will provide to users are command-line tools.

> * No proc2 implementation
> * client-driven backup-restore
> * basic security: only super user is allowed to run backup/restore
