Huh, RB proxy error ate my comment. I was speaking to some of the HBase team about this yesterday, and they mentioned that they do not support replicated bulk import. Their recommended solution is just to externally copy files and run bulk import on the slave. Since this is something that is possible for users to configure themselves, I'd like to make sure we focus on the difficult case of like ingest. Is the assumption that replication is an all-or-nothing deal? Either you replicate all of the tables on a system, or you replicate none of them, but just a defined set is not allowed? I believe the WAL groups mutations by table IDs, so care would need to be taken to make sure those do not get out of sync. What happens when I clone a table, for example when running an offline MR job. does the clone need to be replicated? I assume no. If the slave is a read-only implementation, can I make clones there to run MR? Maybe another thing that will come out of this is 'transient clones' that have IDs in a reserved high range that can be reused after they are deleted. - Mike ----------------------------------------------------------- This is an automatically generated e-mail.
