-------------------------------------
Summary: When the table is turned on normalize, the first region
may not be merged even the size is 0
Key: HBASE-25513
URL: https://issues.apache.org/jira/browse/HBASE-25513
Project: HBase
Issue Type: Bug
Components: Normalizer
Affects Versions: 2.4.1, 3.0.0-alpha-1
Reporter: Baiqiang Zhao
Assignee: Baiqiang Zhao
Suppose a table has 8 regions, the sizes are [0, 10, 1, 0, 9, 0, 12, 0], the
average region size is 4, and split is disabled.
The current Normalizer can only get three merge plans (use size to represent
region):
[1, 0], [9, 0],[12, 0]
It can not merge the first region, even it's size is 0.
