AWS emr: Note EMR WAL does not support ASYNC_WAL durability
Summary
Added a limitation stating Amazon EMR WAL does not support HBase tables or mutations using the ASYNC_WAL durability setting.
Security assessment
Documents a durability/data-integrity limitation of the write-ahead log feature (ASYNC_WAL writes are not guaranteed durable), which is security-adjacent but not a vulnerability fix or security feature documentation.
Evidence
* Amazon EMR WAL does not support HBase tables or mutations that explicitly use the `ASYNC_WAL` durability setting.
