Is it possible to use the BucketingSink that ships with Apache Flink to write data into s3?
I have tried several combinations of the URL but I can't seem to get anywhere with s3
e.g. s3://bucket/path/to/folder
I can write to hdfs when deployed to EMR 5.4.0 but not s3.
The documentation doesn't mention S3 as a potential integration but I am assuming it is supported natively.
https://ci.apache.org/projects/flink/flink-docs-release-1.2/dev/connectors/filesystem_sink.html
I get the following error if I use the s3a:// url format
java.lang.NoSuchMethodError: org.apache.http.params.HttpConnectionParams.setSoKeepalive(Lorg/apache/http/params/HttpParams;Z)V
