Kousuke Saruta 7f3718842c [SPARK-4282][YARN] Stopping flag in YarnClientSchedulerBackend should be volatile 
In YarnClientSchedulerBackend, a variable "stopping" is used as a flag and it's accessed by some threads so it should be volatile.

Author: Kousuke Saruta <sarutak@oss.nttdata.co.jp>

Closes #3143 from sarutak/stopping-flag-volatile and squashes the following commits:

YARN DIRECTORY LAYOUT

Hadoop Yarn related codes are organized in separate directories to minimize duplicated code.

  • common : Common codes that do not depending on specific version of Hadoop.

  • alpha / stable : Codes that involve specific version of Hadoop YARN API.

alpha represents 0.23 and 2.0.x stable represents 2.2 and later, until the API changes again.

alpha / stable will build together with common dir into a single jar
