> Key: CAMEL-10097
> URL: https://issues.apache.org/jira/browse/CAMEL-10097
> Project: Camel
> Issue Type: Bug
> Components: camel-aws
> Affects Versions: 2.15.1, 2.17.1
> Reporter: Raghavan Aravamudhan
> Assignee: Andrea Cosentino
> Labels: aws-s3
>
> I'm a beginner to apache camel framework and i'm using 2.17.1 version. My use
> case is to periodically sync newly created files in s3 to local folder in
> linux in java, for which i'm using camel aws-s3 component.
> I'm using deleteAfterRead=false, not to delete files in s3 after download and
> idempotentConsumer for not to poll and download duplicate files again and
> again.
> RouteBuilder
> from("aws-s3://" + Constants.BUCKET_NAME +
> "?amazonS3Client=#client&deleteAfterRead=false")
> .idempotentConsumer(header("CamelAwsS3Key"),
> FileIdempotentRepository.fileIdempotentRepository(new File("data",
> "repo.dat")))
> .routeId("awsFileCopyRoute")
> .log(LoggingLevel.INFO, "awsFileCopyRoute", "Camel AWS Key:
> ${header.CamelAwsS3Key}")
> .to("file://" + Constants.REQ_FOLDER +
> "?fileName=${header.CamelAwsS3Key}");
> In applicationContext.xml, i'm setting amazonS3Client's client bean as
> follows
> <bean id="defaultAWSCredentialsProviderChain"
> class="com.amazonaws.auth.DefaultAWSCredentialsProviderChain" />
> <bean id="clientConfiguration" class="com.amazonaws.ClientConfiguration" />
> <bean id="client" class="com.amazonaws.services.s3.AmazonS3Client">
> <constructor-arg ref="defaultAWSCredentialsProviderChain" />
> <constructor-arg ref="clientConfiguration" />
> </bean>
> It's working first time downloading non-duplicate files from s3 to the
> REQ_FOLDER, but the issue is after 1 min, i've been getting following
> exception repeatedly.
