Lookups broken with Druid 0.9.1-rc3 #223

Closed arnaudbriche closed 8 years ago

arnaudbriche commented 8 years ago

Hi,

I'm experiencing with Druid 0.9.1-rc3 and all my lookups are broken. Each time I choose a dimension with lookup to split or filter, I get the following message from Druid:

{
    "error": "could not compute","message":"Could not resolve type id 'namespace' into a subtype of [simple type, class io.druid.query.lookup.LookupExtractor]\n at [Source: HttpInputOverHTTP@7944ef52; line: 1, column: 283]"
}

Here is a dimension definition using lookup from my Pivot config file:

  - name: Campaign
    title: Campaign
    expression: $Campaign.lookup('test_mapping').fallback($Campaign)

I run Pivot version 0.8.42.

@arnaudbriche, lookup configurations & query syntax in 0.9.1-rc3 are not compatible with 0.9.0 due to changes in the lookup framework. The 0.9.1 final release (& some future RC as well) will likely include a compatibility layer to make migration to the new framework easier. Pivot/Plywood would support both on the query side, although you would have to migrate configs.

Some more details about the new framework are in the release notes: https://github.com/druid-io/druid/issues/2999

Ok, I missed this information. Thanks guys

I am going to keep this issue open for now because I think it is helpful for anyone trying out Druid 0.9.1-rc right now. I'll close it once Pivot can actually handle the new lookups and had old lookup fallback capabilities.

Alright. Pivot 0.9.1 released with full support for Druid 0.9.1 (the versions are a coincidence). Please read the lookup migration instructions.
