> Start up a four-node HDFS cluster in 2.10.2 version.
> Execute the following commands. (The client is started up in NN, We have
> minimized the command sequence for reproducing)
> {code:java}
> bin/hdfs dfs -mkdir /GUBIkxOc
> bin/hdfs dfs -put -f -p -d /tmp/upfuzz/hdfs/GUBIkxOc/bQfxf /GUBIkxOc/
> bin/hdfs dfs -mkdir /GUBIkxOc/sKbTRjvS{code}
> Perform read in the old version
> {code:java}
> bin/hdfs dfs -ls -t -r -u /GUBIkxOc/
> Found 2 items
> drwxr-xr-x - root supergroup 0 1970-01-01 00:00 /GUBIkxOc/sKbTRjvS
> drwxr-xr-x - 20001 998 0 2023-04-17 16:15

> perform the same read
