[jira] [Created] (HBASE-7850) Bulkload final step can detect and pre-split tables

Harsh J created HBASE-7850:
------------------------------

             Summary: 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.
