Jason Lowe commented on YARN-4814:
----------------------------------
Sorry I missed this before it went in. Don't we have an issue where we're no
longer flushing the json generator? The flush thread flushes the output stream
directly and _not_ the json generator, so don't we risk missing data that has
been buffered in the generator itself? I think we either need to call flush on
the json generator when the flush timer task executes or set
FLUSH_PASSED_TO_STREAM to false on the json generator rather than setting
FLUSH_AFTER_WRITE_VALUE on the object mapper.
