Known Issues and Limitations
- Impersonation is not supported for Kafka REST Proxy for HPE Ezmeral Data Fabric Streams. Kafka REST is
run as mapr user which means that you must explicitly give mapr user
permissions to consume and produce from/to streams. For example, the
consumeperm
parameter must be set to mapr user to be able to consume and theproduceperm
parameter must be set to mapr user to be able to produce.
