---------------------------------------
Summary: Incompatible JNA libraries cause unnecessary failures
when using cassandra-all jar.
Key: CASSANDRA-16615
URL: https://issues.apache.org/jira/browse/CASSANDRA-16615
Project: Cassandra
Issue Type: Bug
Components: Local/Other
Reporter: Doug Rohrer
There are some additional use-cases where lack of JNA libraries is causing
issues for users of cassandra-all libraries - cases where the native libraries
were not loaded but we should be able to continue should be handled without
throwing exceptions. Note that the Cassandra +server+ will not start up without
an appropriate/compatible JNA jar available, but users of the cassandra-all
libraries will have a more difficult time maintaining compatibility across JNA
versions as they deploy to, for example, Spark setups that have newer/older JNA
versions.
Proposal:
- Audit usages of `NativeLibrary`
- Wherever possible, handle the -1 return values without failing +if
`DatabaseDescriptor.isClientInitialized()` returns true+.
- Maintain existing failure behavior if the system is not in client mode but
the call returns -1.
