Jim Kellerman commented on HBASE-1535:
--------------------------------------
There ought to be a neon flashing sign on this option.
As for bulk import, would you use that on an existing table that had data in
it? You *could* get around the replication problem by shutting down the other
replica(s) that are accepting a feed from the replica getting
the bulk update, then shut it down and copy the table(s) to the other HDFS(s).
> Add client ability to perform mutations without the WAL

> There are a number of cases where a client might not want/need its edits to
> be written into the HLog. The most obvious use of this would be during a
> bulk import where we want the best performance possible and data loss is
> acceptable (can rerun the import).
> Does this become a flag on Put or a special mode of HTable?
