contents of driver.conf file is getting overwritten after starting cosbench driver script

[ksingh7]

Problem : The contents of driver.conf file is getting changed / overwritten after starting cosbench driver.

Here is what i have tried.
To configure cosbench driver node, i manually edited conf/driver.conf with name and url , as shown below

[root@client2 0.4.2.c3]# cat conf/driver.conf 
[driver]
name=client2
url=http://10.5.13.102:18088/driver

As soon as i am running start-driver.sh script

[root@client2 0.4.2.c3]# sh start-driver.sh

[root@client2 0.4.2.c3]# 

The contents of conf/driver.conf file that i updated previously are getting changed to loop back IP , as below

[root@client2 0.4.2.c3]# cat conf/driver.conf 
[driver]
name=127.0.0.1:18088
url=http://127.0.0.1:18088/driver
[root@client2 0.4.2.c3]# 

Here are the output of related files

[root@client2 conf]# cat driver_template.conf
[driver]
name=driver
url=http://127.0.0.1:18088/driver
[root@client2 conf]# cat driver_1.conf
[driver]
name=127.0.0.1:18088
url=http://127.0.0.1:18088/driver
[root@client2 conf]# cat driver.conf
[driver]
name=127.0.0.1:18088
url=http://127.0.0.1:18088/driver
[root@client2 conf]# 
[root@client2 conf]# 

To reverify it , again i edited driver.conf and executed start-driver.sh and repeatedly found that the contents of driver.conf changes back to loopback ip

[root@client2 conf]#  cat driver_1.conf
[driver]
name=client2
url=http://10.5.13.102:18088/driver
[root@client2 conf]# cat driver.conf
[driver]
name=client2
url=http://10.5.13.102:18088/driver
[root@client2 conf]# 
[root@client2 0.4.2.c3]# sh start-driver.sh

Is this a known thing or a bug ?

I should have replied this question before, but weirdly, it's not appearing here. anyway, here is a re-reply.

cosbench supports to launch multiple drivers on one host, so it uses conf/driver_template.conf as template for driver.conf, changes on driver.conf will take no effect, you'd change driver_template.conf instead.
