Load extension dependencies so slowly

Hi:

I have the extension dependencies in local, and change the setting -Ddruid.extensions.localRepository= -Ddruid.extensions.remoteRepositories=. But it seems spend so many time to load these dependencies when start the task.

How to improve the loading performance?

Extension loading had a MAJOR overhaul in 0.9.0 due to multiple problems related to the old way hitting the internet when it shouldn’t.
See http://druid.io/docs/0.9.0-rc3/operations/including-extensions.html for the docs for the release to go out very soon and please test the RC and see if that solves your issues.
