To: chukwa-dev@hadoop.apache.org Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit X-Virus-Checked: Checked by ClamAV on apache.org Hi, I changed my number of reducers from 2 to 1 and that fixed the problem. Does the MultipleOutputFormat require that writes to the same file be performed by only one reduce?
