Description

flume-ng (version 1.2.0) fails while writing to S3 sink since it gets back 404 response code. The files with data is created on S3 though.

Hadoop version used is 0.20.2-cdh3u4

Followed all the steps documented in the jira - https://issues.cloudera.org/browse/FLUME-66
and also I tried swapping out hadoop-core.jar that comes with CDH, with emr-hadoop-core-0.20.jar that comes with EC2 hadoop cluster instance as suggested in the following blog post - http://eric.lubow.org/2011/system-administration/distributed-flume-setup-with-an-s3-sink/ but the issue still remains.

Following errors are seen in the log:
