--------------------------------
Summary: YARN InMemorySCMStore properties need fixing
Key: YARN-2927
URL: https://issues.apache.org/jira/browse/YARN-2927
Project: Hadoop YARN
Issue Type: Bug
Affects Versions: 2.6.0
Reporter: Ray Chiang
Assignee: Ray Chiang
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.
