Ted Yu commented on HBASE-4552:
-------------------------------
Toward the end of LoadIncrementalHFiles.tryLoad() we can utilize startEndKeys
of the underlying table to group (possibly split) HFiles by their first row
keys.
Then the new bulkLoadHFile() method would be called by doBulkLoad().
> multi-CF bulk load is not atomic across column families

> URL: https://issues.apache.org/jira/browse/HBASE-4552
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 0.92.0
> Reporter: Todd Lipcon
> Fix For: 0.92.0
>
>
> Currently the bulk load API simply imports one HFile at a time. With
> multi-column-family support, this is inappropriate, since different CFs show
> up separately. Instead, the IPC endpoint should take a of CF -> HFiles, so we
> can online them all under a single region-wide lock.
