XML map file name is constant

[alespouzar]

It's not save to run more than one Writer job at the same time as XML mapping file name is constant (map_file.xml). So one job can rewrite mapping file of another running job (files are uploaded to the same directory "uploads"). Mapping file should have unique name (e.g. using random string or at least database/list id).

Example:
Job 1: (CZ contacts):
Source file: contacts.csv (filter on column COUNTRY = CZ)
Target: CZ database (id 1234)

Job 2 (SK contacts):
Source file: contacts.csv (filter on column COUNTRY = SK)
Target: SK database (id 5678)

Both files can be uploaded nearly at the same time so API job for CZ can read mapping file for SK (i.e. SK contacts would be imported to CZ database) or vice versa.

Could you please fix this issue?
