Description

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
