Hi, I'm trying to set up Checkpoints for Flink Jobs with S3 as a filesystem backend. I configured the following:
state.backend=filesystem state.backend.fs.checkpointdir=s3:///mybucket/ state.checkpoints.dir=s3:///mybucket/ state.checkpoints.num-retained=3 I also copied the flink-s3-fs-hadoop-1.5.0.jar into the lib folder. I get now though the following error message: Caused by: java.lang.NullPointerException: null uri host. at java.util.Objects.requireNonNull(Objects.java:228) at org.apache.flink.fs.s3hadoop.shaded.org.apache.hadoop.fs.s3native.S3xLoginHelper.buildFSURI(S3xLoginHelper.java:65) at org.apache.flink.fs.s3hadoop.shaded.org.apache.hadoop.fs.s3a.S3AFileSystem.initialize(S3AFileSystem.java:165) at org.apache.flink.fs.s3hadoop.S3FileSystemFactory.create(S3FileSystemFactory.java:133) I tried to dig deeper into the source code, but struggled to find - what is meant with this URI - where to configure it Can anybody give some advice how to set up the S3 Backend with the new shaded lib jar?
