Method Detail

createLocalKVSecurity

protected static void createLocalKVSecurity(String clientLoginFile,
                         String serverLoginFile)
                                     throws IOException

Creates the artifacts required to connect to and interact with a secure store; specifically, a login file, a trust file, and PasswordCredentials. To create the login and trust files in the local file system, this method uses the given file names to retrieve the contents of each respective file as a resource from the classpath and then writes the contents to the local file system, in a directory owned by the application. This is done so that this information is available to the frontend, client-side of the application when attempting to connect to a secure store.

This method also caches the names of the given files (as well as the PasswordCredentials) so that this information can be retrieved and sent to another party, such as the backend, server-side of an application; for example, the InputFormat and InputSplits of a MapReduce job.

Throws:

IOException
