====== Modify Big Data Storage Location ======

By default, the Big Data Service creates a data file repository under the install location:

   * C:\Program Files\Intelligent Plant\Big Data\es\data

To set this to an alternative location (e.g. a dedicated data volume) do the following:

**1. Stop the Big Data Service**

Open Windows Services. \\
Find “Intelligent Plant Big Data Service”. \\
Right click, then select “Stop”.

**2. Move data folder**

Move data folder "C:\Program Files\Intelligent Plant\Big Data\es\data" to preferred location (e.g. D drive)

**3. Edit Elasticsearch configuration file**

Open "C:\Program Files\Intelligent Plant\Big Data\es\config\elasticsearch.yml" \\
This is a text file using YAML format that can be edited in most text editors. \\
Uncomment line containing the “path.data” key and set to the new data folder location.
