Does the YCSB dynamodb client support AWS roles and session tokens. Appears to fail
The only thing i am doing differently is storing the assess key and secret key along with security key and session token for the role in the credentials file in the below format

Note

YCSB/bin/ycsb load dynamodb -P /home/scyllaadm/YCSB/dynamodb/conf/dynamodb.properties -p dynamodb.partition_key=firstname -P workloads/workloada
