To move from

/user/hdfs/.Trash/Current/<your file>

Use the -cp command, like this

hdfs dfs -cp /user/hdfs/.Trash/Current/<your file> <destination>

Also you will find that your dir/file name is changed you can change it back to whatever you want by using '-mv' like this:

hdfs dfs -mv <Your deleted filename with its path> <Your new filename with its path>

Example:

hdfs dfs -mv /hdfs/weirdName1613730289428 /hdfs/normalName

Before moving back your directory, you should locate where your file is in:

hadoop fs -lsr /user/<user-name>/.Trash | less

Eg, you may found:

-rw-r--r--   3 <user-name> supergroup     111792 2020-06-28 13:17 /user/<user-name>/.Trash/200630163000/user/<user-name>/dir1/dir2/file

If dir1 is your deleted dir, move it back:

hadoop fs -mv /user/<user-name>/.Trash/200630163000/user/<user-name>/dir1 <destination>

Did you try cp or mv? e.g.,

hdfs dfs -cp -r /user/hdfs/.Trash/Current/ /hdfs/Current
