Subject Re: Flume collectors started crashing regularly all of a sudden
Date Tue, 22 Nov 2011 16:26:42 GMT
I'm not sure, in your log I see a lot of 404 instead 200 (means that some
buckets could not be load) from a s3 instance
(org.jets3t.service.impl.rest.httpclient.RestS3Service). All warnings
concerns the same file (0025 at the end), and at least flume will give up.
Looks for me like a S3 problem to write the file (s3n://
hooklogic-data-east/flume/%Y/%m/%d/%H","syslog")

best,
 Alex
