Billie Rinaldi updated YARN-5808:
---------------------------------
Attachment: YARN-5808-yarn-native-services.001.patch
[~gsaha] Attaching a patch. I learned that env vars like YARN_SERVICESAPI_OPTS
are automatically added to the classpath, but we have to remove the dash from
the services-api command to make this work properly, making it servicesapi. I
added a commented-out example to yarn-env.sh that sets this variable. I based
the example on the RM example opts in the same file, so the file name is
gc-servicesapi.log-<date>. There is a different example for the RM opts that
uses a global HADOOP_GC_SETTINGS variable, so people might want to use that for
the services API instead as well. Also, I learned that YARN_CLIENT_OPTS is
added automatically, so we don't have to do that for slider or servicesapi.
