Hi, There're two copies of classes w.r.t. YARN: -rw-r--r-- 1 tyu staff 9710 Jan 3 10:14 /Users/tyu/spark//yarn/alpha/src/main/scala/org/apache/spark/deploy/yarn/WorkerLauncher.scala -rw-r--r-- 1 tyu staff 8189 Jan 3 10:14 /Users/tyu/spark//yarn/stable/src/main/scala/org/apache/spark/deploy/yarn/WorkerLauncher.scala
The class under yarn/stable is for YARN 2.2, right ? Cheers
