Vladimir Rodionov commented on HBASE-14417:
-------------------------------------------

{quote}
Patch v24 registers tables being fully backed up in zookeeper so that BulkLoadHandler on respective
region server can avoid unnecessary post to zookeeper.
{quote}

Why can not we use hbase:backup table for that?

> Currently, incremental backup is based on WAL files. Bulk data loading bypasses WALs
for obvious reasons, breaking incremental backups. The only way to continue backups after
bulk loading is to create new full backup of a table. This may not be feasible for customers
who do bulk loading regularly (say, every day).
