After region split, new daughter regions contain the reference of the original
HFile until compaction happens.
In RestoreSnapshotHelper (while restoring snapshot file which have regions
containing hfile references), path is initialized using the snapshot table name
which has namespace separated by colon,
{code}
private void restoreReferenceFile(final Path familyDir, final HRegionInfo
regionInfo,
final String hfileName) throws IOException {
// Extract the referred information (hfile name and parent region)
Path refPath = StoreFileInfo.getReferredToFile(new Path(new Path(new Path(
snapshotTable.getNameAsString(), regionInfo.getEncodedName()),
familyDir.getName()),
hfileName));

}
