Esteban Gutierrez created HBASE-18024:
-----------------------------------------
Summary: HRegion#initializeRegionInternals should not re-create
.hregioninfo file when the region directory no longer exists
Key: HBASE-18024
URL: https://issues.apache.org/jira/browse/HBASE-18024
Project: HBase
Issue Type: Bug
Components: Region Assignment, regionserver
Affects Versions: 1.2.5, 1.3.1, 1.4.0
Reporter: Esteban Gutierrez
Assignee: Esteban Gutierrez
When a RegionSever attempts to open a region, during initialization the RS
tries to open the {{<hbase.root.dir>/data/<table>/<region>/.hregioninfo}} file,
however if the {{.hregioninfofile}} doesn't exist, the RegionServer will create
a new one on {{HRegionFileSystem#checkRegionInfoOnFilesystem}}. A side effect
of that tools like hbck will incorrectly assume an inconsistency due the
presence of this new {{.hregioninfofile}}
