https://community.cloudera.com/t5/Support-Questions/Authentication-for-Amazon-s3-using-Temporary-credentials-STS/m-p/62739#M22581 Hi,<BR /><BR />Just to add some information. We tried to execute this code : <A href="https://github.com/satishpandey/aws-spark-samples/blob/master/src/com/spark/aws/samples/s3/SparkS3STSAssumeRole.java" target="_blank">https://github.com/satishpandey/aws-spark-samples/blob/master/src/com/spark/aws/samples/s3/SparkS3STSAssumeRole.java</A><BR />But we had issues due to the hadoop properties. The "session.token" property seems to never be used when we set the "fs.s3n.awsSecretAccessKey" and "fs.s3n.awsAccessKeyId" properties.<BR /><BR /><BR />Does anyone succeded to use aws sts in a spark code ?<BR />We don't know if we have an issue regarding our configuration settings in the use of the properties or in the temporary credentials generation.<BR /><BR />Regards, Wed, 13 Dec 2017 14:21:18 GMT slemoing 2017-12-13T14:21:18Z
