Introduced in https://github.com/pwendell/spark/commit/f7e79bc42c1635686c3af01eef147dae92de2529, I'm not sure why we need two spark.executor.memory here.

[SPARK-3067] JobProgressPage could not show Fair Scheduler Pools section sometimes

JobProgressPage could not show Fair Scheduler Pools section sometimes.
SparkContext starts webui and then postEnvironmentUpdate. Sometimes JobProgressPage is accessed between webui starting and postEnvironmentUpdate, then the lazy val isFairScheduler will be false. The Fair Scheduler Pools section will not display any more.

[SPARK-3606] [yarn] Correctly configure AmIpFilter for Yarn HA (1.1 vers...

...ion).

This is a backport of SPARK-3606 to branch-1.1. Some of the code had to be
duplicated since branch-1.1 doesn't have the cleanup work that was done to
the Yarn codebase.

I don't know whether the version issue in yarn/alpha/pom.xml was intentional,
but I couldn't compile the code without fixing it.
