---------------------------------
Summary: Limiting region count results in large size regions
Key: HBASE-20613
URL: https://issues.apache.org/jira/browse/HBASE-20613
Project: HBase
Issue Type: Bug
Components: regionserver
Reporter: Biju Nair
Restricting the total number of regions in a {{namespace}}, results in large
regions. Not sure whether it is by design i.e. restrict the number of region
even if the region sizes grow large. Steps to recreate.
- Create a namespace with restriction on the number of regions
{noformat}
create_namespace 'ns2',
{'hbase.namespace.quota.maxtables'=>'2','hbase.namespace.quota.maxregions'=>'5'}{noformat}
- Create a table and run {{PE}} to load data. The table can be created with a
small _hbase_._hregion_._max_._filesize_
- After 5 regions, the region size grows beyond
_hbase_._hregion_._max_._filesize._ Since the region count restriction prevents
splits, the region size grows
Will it be better to gracefully error out when regions can't be split?
