Nick Dimiduk commented on HBASE-7850:
-------------------------------------
When you say "final step of bulkload", are you speaking of the CompleteBulkLoad
application, or a MR job ending in HFileOutputFormat?
> Bulkload final step can detect and pre-split tables

> Key: HBASE-7850
> URL: https://issues.apache.org/jira/browse/HBASE-7850
> Project: HBase
> Issue Type: Improvement
> Components: Client
> Reporter: Harsh J
> Priority: Minor
>
> Many new devs (read: POC folks?) aren't aware of the pre-split feature of
> table creation, given that its mostly manual. This leads to situations where
> a huge amount of data gets loaded into a single or a small set of regions,
> causing further issues such as non-assignment or lack of performance.
> Given that the final step of bulkload has a good picture of what they keys
> may look like, it could split the table first if it detects certain
> conditions (we can go over this in comments) and then perform the bulkload.
