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.
