Major Description
There should be verification during DataNode startup that SSL is configured correctly and working before the DataNode advertises availability. If SSL is not configured correctly – such as a bad configuration key or corrupt keystore file – services making connections via SSL (swebhdfs as an example) will encounter issues when attempting to retrieve data from misconfigured nodes. This verification check will prevent misconfigured DataNodes from advertising that they are working correctly while also providing a feedback mechanism to state that it is misconfigured.
If SSL is misconfigured it should prevent startup from continuing, shutting down the process.
