Potential bug when assuming roles from AWS EKS when using S3 as RocksDb checkpoint backend?

Hi, I'm using the official docker image: apache/flink:1.12.1-scala_2.11-java11 I'm trying to run a Flink job on an EKS cluster. The job is running under a k8s service account that is tied to an IAM role. If I'm not using s3 as RocksDB checkpoint backend, everything works just fine. However, when

Hi Thomas, did you try to login to EKS node and run some aws command like : aws s3 ls ? It sounds like EKS issue, but not 100% sure. Best On Sat, 25 Sept 2021 at 22:12, Ingo Bürk wrote: > Hi Thomas, > > I think you might be looking for this: > https://github.com/apache/flink/pull/16717 > > > Be

We need to overwrite using    WebIdentityTokenFileCredentialsProviderhttps://github.com/aws/aws-sdk-java-v2/issues/1470#issuecomment-543601232.  otherwise java takes presidency to secret key and access keys than SA On Saturday, September 25, 2021, 04:37:22 PM EDT, Xiangyu Su wrote: Hi

Hi, Puneet Could you share whether you are using Flink's session mode or application mode? >From the log, you are using `StandaloneDispatcher`, but you will use it in both session and application mode. If you use application mode, this might be in line with expectations. Best, Guowei On Fri, Se

Re: Write Streaming data to S3 in Parquet files

Hi, Harshvardhan I think CaiZhi is right. I only have a small addition. Because I see that you want to convert Table to DataStream, you can look at FileSink (ParquetWriterFactory)[1]. [1] https://ci.apache.org/projects/flink/flink-docs-master/docs/connectors/datastream/file_sink/#bulk-encoded-for

Re: Potential bug when assuming roles from AWS EKS when using S3 as RocksDb checkpoint backend?

Ingo, It looks like I'm now seeing "Caused by: java.lang.NullPointerException: You must specify a value for roleArn and roleSessionName". I assume I would also need to specify that through the configuration file. Could you suggest the key for this configuration? Thanks. Thomas On Sat, Sep 25, 20

Re: Potential bug when assuming roles from AWS EKS when using S3 as RocksDb checkpoint backend?

Ingo, I dig into the Flink code a little bit. It looks like the key for specifying the roleArn and roleSessionName are fs.s3a.aws.credentials.provider: com.amazonaws.auth.WebIdentityTokenCredentialsProvider fs.s3a.aws.credentials.provider.role.arn: arn:aws:iam::...:role/... fs.s3a.aws.credentials.
