Metadata error

#1

Hi just downloaded HI and trying to create metadata from the travel CSV sample…following error

“Error: MetadataRetrievalException: Couldn’t retrieve metadata as the request does not have parameter called ‘metadata’”

Here’s the csv-model.json…the directory path is correct i.e. I can navigate to it :slight_smile: Am I missing something?

inline: {
version: ‘1.0’,
defaultSchema: ‘Travel’,
schemas: [
{
name: ‘Travel’,
type: ‘custom’,
factory: ‘org.apache.calcite.adapter.csv.CsvSchemaFactory’,
operand: {
directory: ‘c:/Helical Insight/hi-repository/1463377807724/1472040223535/Travel’
}
}
]
}

Hi Gabryr,

Thank you for your query.

There is no issue with the details you have shared. The steps you have followed for creating a metadata in case of CSV differd. Instead of selecting “Create”, select “Workflow”.

Following are the steps involved in creating metadata for CSV Datasource:

Step1 : Configure JSON file by providing folder path in which CSV file/'s are available.
Please refer to csv-model.json file

Step2 : Configure EFWD file : It consist of datasource connection details and JSON file path.
You can refer to sample.efwd file

Step3 : After configuration, login to Helical Insight.

Step4 : Click on Home Button ( on top left side ) then click “Adhoc”.

Step5 : Now, click on “Metadata” , select “Workflow”.

Step6 : Select Datasource Type "Virtual Datasource"

Step7 : Now, click on Datasource Name, in this case "Travel CSV Datasource"
( Datasource name can be renamed in the efwd )

Step8 : Then, select schema name (can be one or more ). Here, select “Travel”.

Step9 : Select required tables from the list and click next.

Step10 : Select required columns from the list and then click next.

Step11 : Now, you will be redirected to metadata view where perform other operations like defining joins and many more. Click here to know more about metadata.

Step12 : Click on “Save” to confirm.
