HBase bulkload fails to load Hfiles - hadoop

Question

I'm trying to load Hfiles to an HBase docker container after an upgrade to Hbase 2.2.3.
My load Hfiles function looks as follows:
public void loadHfiles(String hfilesPath) throws IOException{
Path hfiles = new Path(hfilesPath);
Configuration conf = DataContext.getConfig();
BulkLoadHFiles loader = BulkLoadHFiles.create(conf);
loader.bulkLoad(HbaseDataIndex.dataContext.getTableName(), hfiles);
}
The Hfiles load fails with the following error:
[org.apache.hadoop.hbase.tool.LoadIncrementalHFiles] [WARN ] [main]
Skipping non-directory
file:/hfiles/14-02-2023-19-01-43/rHfiles/R/f0994365fa064243b81db927c18600ac
[org.apache.hadoop.hbase.tool.LoadIncrementalHFiles] [WARN ] [main]
Bulk load operation did not find any files to load in directory
/hfiles/14-02-2023-19-01-43/rHfiles/R. Does it contain files in
subdirectories that correspond to column family names?
My HBase table contains the following schema:
COLUMN FAMILIES DESCRIPTION
{NAME => 'BL', VERSIONS => '1', EVICT_BLOCKS_ON_CLOSE => 'false',
NEW_VERSION_BEHAVIOR => 'false', KEEP_DELETED_CELLS => 'FALSE',
CACHE_DATA_ON_WRITE => 'false' , DATA_BLOCK_ENCODING => 'NONE', TTL =>

{NAME => 'R', VERSIONS => '1', EVICT_BLOCKS_ON_CLOSE => 'false',
NEW_VERSION_BEHAVIOR => 'false', KEEP_DELETED_CELLS => 'FALSE',
CACHE_DATA_ON_WRITE => 'false', DATA_BLOCK_ENCODING => 'NONE', TTL =>

COMPRESSION => 'NONE', BLOCKCACHE => 'true', BLOCKSIZE => '65536'}
I checked and the Hfiles exist on the Hbase container under /hfiles/14-02-2023-19-01-43/rHfiles/R/f0994365fa064243b81db927c18600ac with all the permission r/w/x.
In my previous HBase version 2.1.0 my load Hfiles function looked as follows:
Connection conn = ConnectionFactory.createConnection(DataContext.getConfig());
Admin admin = conn.getAdmin();
Table table = conn.getTable(DataContextataContext.getTableName());
RegionLocator regionLocator = conn.getRegionLocator(HDataContextataContext.getTableName());
LoadIncrementalHFiles load = new LoadIncrementalHFiles(HbaseDataIndex.dataContext.getConfig());
load.doBulkLoad(new Path(hfilesPath), admin, table, regionLocator);
It worked fine. In the new version, I saw that LoadIncrementalHFiles is deprecated, therefore I used the implementation above with BulkLoadHFiles.
What am I doing wrong here?
Must Hfiles be on HDFS/S3 in the new BulkLoadHFiles implementation?
