A name like "/home/wdssii/data/KTLX/code_index.lb is mapped to a unique table name such as table_13 Users refer to the table using the full path, but SQL queries have to refer to things using the 32-byte name.

Because every host will have its own such table, the fullName should not include the machine name in it.
