> The current implementation for restore uses WALReplay M/R job. This has
> performance and stability problems, since it uses HBase client API to insert
> data. We have to migrate to bulk load approach: generate hfiles directly from
> snapshot and incremental images. We run separate M/R job for every backup
> image between last FULL backup and current incremental backup we restore to
> and for every table in the list (image). If we have 10 tables and 30 days of
> incremental backup images - this results in 30x10 = 300 M/R jobs. MUST be
> optimized.
