>                 URL: https://issues.apache.org/jira/browse/YARN-2927
>             Project: Hadoop YARN
>          Issue Type: Sub-task
>    Affects Versions: 2.6.0
>            Reporter: Ray Chiang
>            Assignee: Ray Chiang
>              Labels: newbie, supportability
>             Fix For: 2.7.0

> I see these properties in the yarn-default.xml file:
>   yarn.sharedcache.store.in-memory.check-period-mins
>   yarn.sharedcache.store.in-memory.initial-delay-mins
>   yarn.sharedcache.store.in-memory.staleness-period-mins
> YarnConfiguration looks like it's missing some properties:
>   public static final String SHARED_CACHE_PREFIX = "yarn.sharedcache.";
>   public static final String SCM_STORE_PREFIX = SHARED_CACHE_PREFIX + "store.";
>   public static final String IN_MEMORY_STORE_PREFIX = SHARED_CACHE_PREFIX + "in-memory.";
>   public static final String IN_MEMORY_STALENESS_PERIOD_MINS = IN_MEMORY_STORE_PREFIX
+ "staleness-period-mins";
> It looks like the definition for IN_MEMORY_STORE_PREFIX should be:
>   public static final String IN_MEMORY_STORE_PREFIX = SCM_STORE_PREFIX + "in-memory.";
> Just to be clear, there are properties that exist in yarn-default.xml that are effectively
misspelled in the *Java* file, not the .xml file.  This is similar to YARN-2461 and MAPREDUCE-6087.
