Subject [jira] [Created] (HDFS-10864) Verify SSL is working on DataNode startup
Date Thu, 15 Sep 2016 16:06:20 GMT
Adam Whitlock created HDFS-10864:

             Summary: Verify SSL is working on DataNode startup
                 Key: HDFS-10864
                 URL: https://issues.apache.org/jira/browse/HDFS-10864
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: datanode, security
            Reporter: Adam Whitlock

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.
