Examples of HFileLink

org.apache.hadoop.hbase.io.HFileLink
HFileLink describes a link to an hfile. An hfile can be served from a region or from the hfile archive directory (/hbase/.archive) HFileLink allows to access the referenced hfile regardless of the location where it is.
Searches for hfiles in the following order and locations:
- /hbase/table/region/cf/hfile
- /hbase/.archive/table/region/cf/hfile
The link checks first in the original path if it is not present it fallbacks to the archived path.
