Unable to resolve artifacts for io.druid.extensions:druid-examples:jar:0.8.0

[Sai Subramaniam]

Hi,

I downloaded Druid-0.8.0 from the tarball (also tried build from source) and ran an example..

[root@sandbox druid-0.8.0]# ./run_example_server.sh 

This will run a stand-alone version of Druid

Please specify an example by its number.

Examples available:

1 - wikipedia/wikipedia_realtime.spec - No Description

2 - twitter/twitter_realtime.spec - No Description

[1] > 1

 

Running command:

I have set the necessary proxy configurations. When I go to https://metamx.artifactoryonline.com/metamx/pub-libs-releases-local, I don't see libraries for druid 0.8, could that be the reason??

As a side question: How is panoramix? Can the UI be used in production?

Thanks.
