Method Detail

isHadoopCredentialProviderAvailable

private boolean isHadoopCredentialProviderAvailable()

Determine if we can load the necessary CredentialProvider classes. Only loaded the first time, so subsequent invocations of this method should return fast.

Returns:

True if the CredentialProvider classes/methods are available, false otherwise.

loadMethod

private Method loadMethod(Class<?> clz,
                          String name,
                          Class<?>... classes)
                   throws Exception

Throws:

Exception

getCredentialProviders

protected List<Object> getCredentialProviders(org.apache.hadoop.conf.Configuration conf)

Wrapper to fetch the configured List<CredentialProvider>s. n * Configuration with GENERAL_SECURITY_CREDENTIAL_PROVIDER_PATHS defined

Returns:

List of CredentialProviders, or null if they could not be loaded

createEntry

public void createEntry(org.apache.hadoop.conf.Configuration conf,
                        String name,
                        char[] credential)
                 throws Exception

Create a CredentialEntry using the configured Providers. If multiple CredentialProviders are configured, the first will be used. n * Configuration for the CredentialProvider n * CredentialEntry name (alias) n * The credential

Throws:

Exception

private void createEntryInProvider(Object credentialProvider,
                                   String name,
                                   char[] credential)
                            throws Exception

Create a CredentialEntry with the give name and credential in the credentialProvider. The credentialProvider argument must be an instance of Hadoop CredentialProvider. n * Instance of CredentialProvider n * CredentialEntry name (alias) n * The credential to store

Throws:

Exception
