What spark jar files serves the following files ..

Hi Everyone,

 Is there any way I could determine what spark service or component serves the following files please refer below and where can I locate this files? I'm assuming it could be part of jar file that is being executed whenever a spark job is completed, however I'm not really sure of it.  Appreciate if someone can point in the right direction on where I could check for this files.

http://<spark-server>/history.bak
http://<spark-server>/history.bz2
http://<spark-server>/history.cfg
http://<spark-server>/history.csv
