Not to continually dog on JNI, but I'd like to point out another downside, and that is portability. Using JNI to connect to the IOCTL requires that the JNI-based Java code be build on all platforms. As a result, each per-node deployment of Hadoop must ensure it's version of the JNI connector was built for that particular architecture. I'm wondering how this will affect Hadoop over Ceph in terms of a sales pitch, given that it could require a configuration headache for large-scale deployments.
