Jim Kellerman updated HADOOP-2496: ---------------------------------- Issue Type: New Feature (was: Bug) > Snapshot of table > ----------------- > > Key: HADOOP-2496 > URL: https://issues.apache.org/jira/browse/HADOOP-2496 > Project: Hadoop > Issue Type: New Feature > Components: contrib/hbase > Reporter: Billy Pearson > Priority: Minor > Fix For: 0.17.0 > > > Havening an option to take a snapshot of a table would be vary useful in > production. > What I would like to see this option do is do a merge of all the data into > one or more files stored in the same folder on the dfs. This way we could > save data in case of a software bug in hadoop or user code. > The other advantage would be to be able to export a table to multi locations. > Say I had a read_only table that must be online. I could take a snapshot of > it when needed and export it to a separate data center and have it loaded > there and then i would have it online at multi data centers for load > balancing and failover. > I understand that hadoop takes the need out of havening backup to protect > from failed servers, but this does not protect use from software bugs that > might delete or alter data in ways we did not plan. We should have a way we > can roll back a dataset. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
