Phabricator updated HBASE-4628:
-------------------------------
Attachment: HBASE-4628.D411.1.patch
cgist requested code review of "HBASE-4628 [jira] Enhance Table Create Presplit
Functionality within the HBase Shell".
Reviewers: nspiegelberg, JIRA
[89-fb] Ported RegionSplitter and TestRegionSplitter from trunk
The RegionSplitter is useful for creating a table pre-split
into many regions, including two different algorithms for splitting
keys. This also includes the patch for HBASE-4627.
Currently, we allow the user to presplit in the HBase shell by explicitly
listing the startkey of all the region shards that they want. Instead, we
should provide the RegionSplitter functionality of choosing a split algorithm,
followed by the number of splits that they want.
TEST PLAN
The TestRegionSplitter test suite.
