Subject [jira] [Created] (HBASE-5940) HBase in-cluster backup based on the HDFS hardlink
Date Fri, 04 May 2012 17:42:50 GMT
Liyin Tang created HBASE-5940:

             Summary: HBase in-cluster backup based on the HDFS hardlink
                 Key: HBASE-5940
                 URL: https://issues.apache.org/jira/browse/HBASE-5940
             Project: HBase
          Issue Type: New Feature
            Reporter: Liyin Tang
            Assignee: Liyin Tang

The motivation of introducing the HardLink operation/api in HDFS is to get a full copy of
the file without copying the bytes. 
So users/applications can create multiple hard links to the same source file instantly. 

And HBase can make full use of the hard-link to generate the in-cluster backup snapshot instantly.
