Hi Kostas,
I tried your PR - trying to write to S3 from Flink running on AWS, and I got
the following error. I copied the three jar files
flink-hadoop-fs-1.7-SNAPSHOT.jar, flink-s3-fs-base-1.7-SNAPSHOT.jar,
flink-s3-fs-hadoop-1.7-SNAPSHOT.jar to lib/ directory. Do I need to make any
change to HADOOP configurations?
Thanks and best regards,
Averell
