Metatron-discovery: Can't create a datasource using metatrone engine

[hashansl]

I'm getting " Name is Null " error. Why is this ? How can I solve this ?

@hashansl Sorry. The test was delayed because I was on a business trip. I will test it today.

@i1befree Okay.. Thank you!

I've tested it and found a hole when importing a datasource directly from druid.
It is reproduced when a granularity is null (or NONE).

I'll fix it and it will be released into the coming version (maybe in this week).

If you want to use this feature faster, please checkout f#1760-engine_granularity_nullcheck branch and rebuild your application.

Thanks for your great contribution @hashansl.
