You have given the table location as '/user/hive/warehouse' . When you load data into that table and if you have used overwrite, first the directory is deleted and then created and new file is loaded.
So here your hive warehouse dir is same as your table location. So when you used Load data with overwrite all the table's dirs also
You can recover the data only if trash is enabled in hdfs.
