How to specify multiple data paths in custom car

Elastic Stack Elasticsearch
1

I've defined a custom car with base=vanilla. I'm trying to set multiple data paths using data_paths, but I'm not sure how to make rally recognize the value.

I've tried

/path/0,/path/1
/path/0/,/path/1/
/path/0, /path/1
/path/0","/path/1
/path/0','/path/1

In the first three cases, it treats the paths as a single string and I end up with

path.data: ['/path/0,/path/1']
path.data: ['/path/0/,/path/1/']
path.data: ['/path/0, /path/1']

in my elasticsearch.yml. In the ones where I explicitly add quotes, the end result uses the opposite quote type to make them a single string. So

/path/0","/path/1

becomes

path.data: ['/path/0","/path/1']

and

/path/0','/path/1

becomes

path.data: ["/path/0','/path/1"]

How can i delimit my strings so that elasticsearch will store in multiple locations?

Hello,

Did you try to specify data_paths via a json file, as described here and use an array e.g.:

{
    "data_paths": ["/mnt/disk1", "/mnt/disk2"]
}

store it as car_params.json and then reference it using car_params=/path/to/car_params.json?

I ended up just changing the elasticsearch.yml file in vanilla to match what I wanted, but thank you for the recommendation!
