Subject [jira] [Commented] (HBASE-17825) Backup: further optimizations
Date Thu, 08 Feb 2018 01:35:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16356347#comment-16356347

Vladimir Rodionov commented on HBASE-17825:
-------------------------------------------

Patch v1 improves incremental backup run time. Now we have only 2 (two) MR jobs instead of
N+1, where N is the number of tables in a backup operation.
