Wangda Tan commented on YARN-7732:
----------------------------------
Thanks [~youchen] for working on this JIRA, could you update the
title/description to better describe what the patch does?
I saw existing AMSimulator is already pluggable:
{code}
// <AMType, Class> map
for (Map.Entry e : tempConf) {
String key = e.getKey().toString();
if (key.startsWith(SLSConfiguration.AM_TYPE_PREFIX)) {
String amType = key.substring(SLSConfiguration.AM_TYPE_PREFIX.length());
amClassMap.put(amType, Class.forName(tempConf.get(key)));
}
}
{code}
I haven't reviewed details of the patch yet, did you meant to add the params to
AMSimulator init method?
Also, this patch updated SynthJob and included the new StreamAMSimulator, could
you elaborate these changes as well?
