Li Lu updated YARN-5314:

    Attachment: YARN-5314-trunk.001.patch

Thanks [~karams] for reporting this issue! The two exceptions are for different reasons, and
let's focusing on the concurrent modification exception in this JIRA (maybe you'd like to
log another one for the leveldb store creation problem? ). In the current patch I did a quick
refactor to clean up the synchronization logic of detail log list, which will address the
problem.
