Charles Allen 2a69a58570 Merge pull request #2149 from binlijin/master 
Do persist IncrementalIndex in another thread in IndexGeneratorReducer
 2016-01-20 17:06:42 -08:00
Charles Allen 2e1d6aaf3d Use thread priorities. (aka set `nice` values for background-like tasks) 
* Defaults the thread priority to java.util.Thread.NORM_PRIORITY in io.druid.indexing.common.task.AbstractTask
 * Each exec service has its own Task Factory which is assigned a priority for spawned task. Therefore each priority class has a unique exec service
 * Added priority to tasks as taskPriority in the task context. <0 means low, 0 means take default, >0 means high. It is up to any particular implementation to determine how to handle these numbers
 * Add options to ForkingTaskRunner
    * Add "-XX:+UseThreadPriorities" default option
    * Add "-XX:ThreadPriorityPolicy=42" default option
 * AbstractTask - Removed unneded @JsonIgnore on priority
 * Added priority to RealtimePlumber executors. All sub-executors (non query runners) get Thread.MIN_PRIORITY
 * Add persistThreadPriority and mergeThreadPriority to realtime tuning config

Bingkun Guo 4914925d65 New extension loading mechanism 
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.
