Junping Du commented on YARN-5915:
----------------------------------
bq. Is the output stream unbuffered such that the write is acting like a flush?
That's also what I am suspecting. Shall we assume the behavior of buffered or
unbuffered output stream be consistent in our case? The _flushBuffer() is hard
to do so. May be good to buffer things at JsonGenerator?

protected final void _flushBuffer() throws IOException
{
int len = _outputTail - _outputHead;
if (len > 0) {
int offset = _outputHead;
_outputTail = _outputHead = 0;
_writer.write(_outputBuffer, offset, len);
}
}
