Each task has a finite lifecycle, so it is expected that some process will be supervising
existing tasks and creating new ones when needed.
1) Remove maven client from downloading extensions at runtime.
2) Provide a way to load Druid extensions and hadoop dependencies through file system.
3) Refactor pull-deps so that it can download extensions into extension directories.
4) Add documents on how to use this new extension loading mechanism.
5) Change the way how Druid tarball is generated. Now all the extensions + hadoop-client 2.3.0
are packaged within the Druid tarball.
- move assembly out of druid-services into a 'distribution' module
- create separate 'extensions-distribution' module and assembly to
package extensions and their dependencies into a local maven
repository
- include this extensions maven repository in the binaries tarball
