             Summary: HBase Backup/Restore Phase 2: Optimized Restore operation
                 Key: HBASE-15331
                 URL: https://issues.apache.org/jira/browse/HBASE-15331
             Project: HBase
          Issue Type: Improvement
            Reporter: Vladimir Rodionov
            Assignee: Vladimir Rodionov


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.
