> Key: YARN-2927
> 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.
